The Springfield Three: Was Graduation Night a Clue to Their Disappearance?

On Sunday, June 7th, 1992, three women—Sherrill Levitt, Suzanne "Suzie" Streeter, and Stacy McCall—vanished from a home in Springfield, Missouri, leaving behind one of America’s most enduring mysteries. Known as "The Springfield Three," their disappearance came just hours after Suzie and Stacy celebrated their high school graduation, a detail that has sparked speculation about whether the timing held deeper significance. The table below outlines their key details:

Name	Age	Gender	Occupation/Status	Last Seen Location	Last Seen Date/Time
Sherrill Levitt NamUS #MP345	47	Female	Hairdresser	Sherrill Levitt’s home at 1717 East Delmar Street, Springfield, MO	Early hours of Sunday, June 7th, 1992
Suzanne "Suzie" Streeter (Sherrill’s daughter) NamUS #MP3233	19	Female	Recent high school graduate, worked at a cinema	Sherrill Levitt’s home at 1717 East Delmar Street, Springfield, MO	Early hours of Sunday, June 7th, 1992
Stacy McCall NamUS #MP350	18	Female	Recent high school graduate	Sherrill Levitt’s home at 1717 East Delmar Street, Springfield, MO	Early hours of Sunday, June 7th, 1992

This article delves into the case, exploring the events of that night and speculating on whether graduation night was more than a coincidence, a theory I propose that aligns with discussions in true crime communities.

A Night of Joy Cut Short

Graduation Festivities

Saturday, June 6th, 1992, marked a milestone for Suzie Streeter, 19, Sherrill Levitt’s daughter, and Stacy McCall, 18, who had both graduated from Kickapoo High School that day. The evening was filled with celebration as the two friends joined classmates at graduation parties. Sherrill, 47, a local hairdresser, stayed home, likely proud of her daughter Suzie’s achievement.

The Disappearance

By 2:00–3:00 a.m. on Sunday, June 7th, 1992, Suzie and Stacy arrived at Sherrill’s home at 1717 East Delmar Street after plans to stay elsewhere fell through. Sherrill’s last known contact was a phone call with a friend around 11:15 p.m. on Saturday, June 6th, 1992. By morning, all three women were gone, their purses, keys, and belongings left untouched in a house showing no signs of a struggle.

The Investigation: A Trail Gone Cold

An Eerie Crime Scene

When friends alerted police later on Sunday, June 7th, 1992, investigators found a clean scene. No forced entry, no blood, no fingerprints—just a broken porch light globe, later deemed unrelated. The family dog was agitated but unharmed, suggesting a swift, controlled abduction. Despite extensive searches and hundreds of tips, no physical evidence has ever conclusively pointed to a suspect.

Theories Without Answers

The case has spawned countless theories: a random predator, a local criminal element, or even a connection to Suzie’s past testimony in a vandalism case. A reported sighting of a green van near the house fueled speculation, but like other leads, it led nowhere. Decades later, the case remains unsolved, with no arrests or solid breakthroughs.

Could Graduation Night Hold the Key?

A Speculative Motive

One intriguing speculation, which I propose, is that the timing of the disappearance—on the night of Suzie and Stacy’s graduation on Saturday, June 6th, 1992—was not just a coincidence. Some true crime enthusiasts on forums like Reddit’s r/UnresolvedMysteries and Websleuths have similarly suggested that graduation, a symbol of triumph and transition, could have triggered a perpetrator with a personal grudge.

Along these lines, to disappear on graduation night might be poetic for someone looking to commit a crime at a perfect time. This theory posits that someone, perhaps feeling sidelined, saw the night as a chance to target the young women at a peak moment of joy. This idea, while unproven, resonates with those who believe the crime was emotionally driven.

The Symbolic Weight of the Night of June 6th-June 7th

High school graduations are laden with meaning. Sociologically, the night, in North American society, could be viewed as a rite of passage: closure of youth, celebration of accomplishment, and the start of adulthood. With a High School diploma in hand, someone can attempt to move on to bigger and better things.

In contrast, for someone harboring resentment, possibly from shared school years, this night could have represented everything they felt denied: acceptance, success, or belonging. For some people, the high school years are socially brutal. From this perspective, the disappearance of The Springfield Three, if it's correct to be understood as an act of some kind of revenge, might connect in some thematic ways to the high school shootings that plagued American society in the years that followed, starting with Columbine about seven years later. These crimes were often committed by high school students among the social outcasts in their schools.

Accordingly, Suzie and Stacy, as recent graduates, might have been symbolic targets for a vindictive person, their abduction a way to disrupt a time that would otherwise be happy for them. This speculation aligns with discussions in true crime podcasts like The Vanished, where listeners have raised ideas about the date’s significance, though no evidence confirms it.

Sherrill’s Role in the Theory

If Suzie and Stacy were the primary targets, Sherrill’s disappearance complicates the narrative. One possibility, discussed in online forums, is that she was an unintended victim—collateral damage as a witness in her own home. The undisturbed scene suggests the perpetrator acted quickly, possibly knowing the house’s layout, which could point to someone familiar with the victims. This idea remains speculative, as no suspect has been linked to such a motive.

Echoes in the True Crime Community

Shared Speculation

The notion that graduation night was significant is a topic in true crime circles, and I’m adding my own perspective to this discussion. On platforms like Reddit and Websleuths, enthusiasts often explore whether the crime felt personal, possibly tied to high school dynamics. I believe it’s important to clarify that the idea of graduation night as a deliberate choice is my own conjecture, though it echoes broader conversations about emotional motives in the case. While these discussions lack hard proof, they highlight a belief among some that the date wasn’t random.

The Day Phyllis Maue Vanished

Phyllis Maue was last seen on June 25th, 1982, which was a Friday.

According to NamUs, she was last seen entering a Chevrolet Van and may have been heading to New York. However, most of the focus on this individual had to do with more local areas where she was last seen. I think searching in New York will likely prove fruitless.

xAI's Grok generated these images when asked to generate an image of a typical Chevrolet Van from the 1977 to 1982 period.

This is a case where I was able to find some journalism on the missing person. Her last known location was in Norwood, Ohio, a suburb or small city to the northeast of Cincinnati, Ohio. A friend last saw her at 2 PM on June 25th, 1982.

The first article on her disappearance that I was able to find appeared in the Cincinnati Enquirer on Wednesday, March 23rd, 1983, titled "Police Ask Help in Finding Woman Missing Since June."

From this article we learn she was married to Greg Maue, she had a ten-year-old son, and that there was a letter from Cincinnati about this case. This letter, which was postmarked to that city, claimed that she was heading to New York City -- which was probably not true, in my opinion.

There were some marital problems in her life as the article above mentions a possible divorce. Another thing that stood out with this case is the letter. What does it mean when someone sends a letter saying that she is going to a far-away city but then is never heard from again?

Before speculating on that, let's stick to known facts. There was a classified advertisement for this missing person that appeared in 2006.

This advertisement claims that she was last in the presence of Samual Ray Phillips (July 1st, 2006; Cincinnati Enquirer), who died in 2004 in a car accident. I think the proper spelling of this person's name was Samuel Ray Phillips, with the "e" in his first name instead of an "a." 

I found a gravemarker on Findagravel.com for a Fairfield man of this name who died in 2004.

By my research, Samual is spelled wrong in this classified ad. Should be Samuel.

Samuel Ray Phillips

Born: November 7th, 1928

Death: January 24th, 2004

Gravemarker suggests a marriage to "Rose M." born in 1934 (possible Rosemary Brown).

Ancestry: This individual is on Ancestry

There was a second piece of journalism on Phyllis Maue in February 2006. Deborah Dixon of The Journal News headlined "Police say missing woman may be tied to Fairfield man." In this article, Ray Phillips is mentioned. It is also stated that police were planning some digs to search for her body. Other important details from this piece of journalism:

• Phyllis left an uncashed paycheque behind. Uncashed assets appear in quite a few missing persons cases. I think it suggests that the person, when last seen, did not plan to disappear voluntarily. If the MP did plan to disappear voluntarily, most would take their negotiables with them.
• Her husband received a nude photo of her in the mail that suggested an extramarital affair with Ray Phillips;
• Reportedly, Maue was going to end the affair on June 25th, 1982.

One interesting fact is that a handwriting expert looked at the letter from Phyllis Maue. He concluded that she did write the letter. However, the handwriting expert also stated that the letter writer was under stress as she wrote.

You have to wonder if an expert of this sort could discern a trembling hand from handwriting. Also, someone under duress might pause while writing -- and this could leave an ink blob. I think her handwriting would have to be compared to normal script. But, for sure, this is not an exact science but rather food for critical thought.

Has Phyllis Maue Been Found?

In my opinion, the totality of the scene suggests that a murder took place. The letter was used as a diversion. I think someone forced her to write it, believing that ostensibly placing her in New York City would explain what was going to be a prolonged...or permanent...absence.

This would help create a diversion and a length of time for the disappearance to be considered voluntary. The more time that passes, the more difficult it is for the authorities to solve the case.

The Van That May Have Taken Michael Dunahee: Could It Be a 1981 Chevrolet P30? Artificial Intelligence Weighs In!

Missing person: Michael Wayne Dunahee

Last-contact date: March 24th, 1991 at about 1230pm; reports surfaced in 2022 of a woman named Norma seeing him twice later that day. It's hard to know what to treat as accurate in situations like these, but the 1230pm time is not disputed.

Updated theory as of March 2025: New Blog Post

Last seen: Victoria, British Columbia on Vancouver Island

It is not disputed that he was at the Blanshard Elementary School playground. The school is no longer there but was at 950 Kings Road and the now-gone playground is on the southwest side of the lot. I would say these Google Maps coordinates are close to the abduction point: 48.437708, -123.360528. Street views on Google Maps only go back to 2009.

The second sighting is taken much more lightly. But it would place him in the custody of a woman 18-25 at a back alley near Wark Street, a little later in the day. Wark Street is a very short road in Victoria extending just two blocks from north to south (Google Maps: Wark Street's northern tip). Wark Street forms a T-intersection at the school on Kings Road.

Michael Dunahee: One of Canada's Best Known Missing Person's Cases

Few missing person cases in Canada's history have generated as much lasting interest as the case of Michael Dunahee. If you, the reader, are among the contingent of people who will undoubtedly look back at the case in March, when the anniversary comes, remember to take a moment to look at the composite sketches and the drawing of the van that Michael was thought to have been lured into. 

A young child (ten years old) said she saw Michael go into a vehicle. This is a witness whose insight into what happened that day can be debated. Children are frivolous and they never make great witnesses. However, there were multiple witnesses who claimed that they saw the brown van, according to a 2022 news article (Hana Nae Nassar/March 8th, 2022/CityNews).

In fact, the Wikipedia page for Michael's disappearance says that there were no witnesses. I think that shows that some discount the child-witness.

In mentioning it, I am not saying it should be taken as fact, but, for me, I think that the child-witness should still be mentioned as food for thought and awareness. So many years have passed since the disappearance that there can't be any harm in keeping an open mind.

Child's Drawing of the Suspect Vehicle

The picture of the van that the young girl drew does not look like that common of a vehicle model. The drawing of the van looks like a small bus or a vehicle that would be used for services like airport transfers.

By my research (from 2021), the vehicle would resemble the Chevrolets in the "P30" and/or "step van" series. These vehicles were on the road in 1991 and seemed to go back several decades with new models hitting the market perhaps annually.

The following is an enlargement of the picture that the girl drew.

 

The full-length door on the side is the biggest clue as to the model in my opinion. While I couldn't find a great non-copyrighted photo, I recommend that the reader go to Google Images and search for "Chevrolet P30 step-van" and then look at the models from 1991 and prior. My top guess for the year, make, and model would be a 1981 Chevrolet P30 Grumman Step Van.

Grok 'Thinks' It IS a 1981 Chevy Step Van

In 2025, I ran the picture through Grok, which is X's artificial intelligence. When I asked what vehicle it was, Grok first stated that it was a 1991 Chrysler Town and Country Minivan. However, I think I had inadvertently limited it to 1991 when I said it was a 1991 drawing.

I decided to ask directly if the vehicle was a Chevrolet Step Van and got the following answer: 

"Based on the analysis, the drawing is most likely of a Chevrolet Step Van, possibly from the mid-20th century, given its boxy shape, three-side-window configuration, and wood-like appearance, which may reflect artistic shading or custom features. While other vehicles like minivans or station wagons were considered, the utilitarian design and forward-control layout align most closely with a step van. This identification reflects the era's use of step vans for delivery and the possibility of custom modifications, fitting the drawing's 1991 creation date as a nostalgic or artistic representation."

For the record, my opinion that it was a Chevy Step Van predated my entry into Grok by four years as the original publication date is February 13th, 2021 for this blog post. I also asked if it was a 1981 Chevrolet P30 Grumman Step Van, which has been my top guess for the last four years, and Grok answered in the affirmative.

"Based on the analysis, the drawing is most likely of a 1981 Chevrolet P30 Grumman Step Van, possibly with custom features like additional windows, given its boxy shape, three-side-window configuration, and wood-like appearance, which may reflect artistic shading or modifications. While other vehicles like minivans or station wagons were considered, the utilitarian design and forward-control layout align most closely with a step van. This identification reflects the era's use of step vans for delivery and the possibility of custom modifications, fitting the drawing's 1991 creation date as a nostalgic or artistic representation."

As a control, I asked if the drawing was of a Volkswagen Beetle, an airplane, or a school bus. Grok answered in the negative, an indicator that the software behind the AI is not just spitting out answers in a biased way. Instead, Grok suggested that it was a step van or minivan. 

"Based on the analysis, the drawing is most likely not a Volkswagen Beetle, an airplane, or a school bus. It seems to depict a van or small truck, possibly a step van or minivan, with a boxy shape, two windows, and a wood-like appearance, which doesn't align with the typical features of the given options. An unexpected detail is that the drawing might represent a customized vehicle, not fitting standard categories, which wasn't among the choices but fits the description better."

I'm not sure what the wood-like appearance meant, except that the color is brown. AI is always just food for thought. File it under "take it or leave it" but I think the chance that the vehicle is of a Chevy Step Van should be noted by anyone interested in this case.

Real-life Footage or Photos of Chevy Step Vans

As far as usable photos go (ie. the photographer allows his/her photo to be used), I found the following. Firstly, I embedded a video below of a 1982 model from Youtube.

The picture below is of a 1997 Chevrolet P30. This is a model that came into the market several years after Dunahee's 1991 disappearance. It was hard to find a user-friendly picture of the models that I wanted to use, which is why I used the 1997 model.

But the earlier models had that long door that you see in the child's drawing. I think it's that feature that is most credible in the drawing, along with the color of the vehicle. The disappearance happened in the early afternoon, and color is easier for the human eye to detect at midday.

Furthermore, the front windows are viewable when taking a side-longed view of the vehicle. This is the kind of vehicle that you might expect to be camperized, used as a food truck, or used for roadside lodging. To me, it suggests that the person who abducted Dunahee was transient or lodged in campgrounds RV parks.

There was an alleged Dunahee sighting in New Jersey in the weeks after Michael disappeared. A shopper at a convenience store named Harry Krusch claimed he saw Michael on April 4th, 1991 in a place called Maple Shade, New Jersey.

An article with the composite sketch of the man who was allegedly in Michael's company is below. I will say that I never really thought much of this alleged sighting of Michael. However, it's also important to remain open-minded. Note, that the composite sketch involved with this alleged sighting is of a black man while the former sketch was of a white person.
