Baby Callum’s Tragic End

In recent news, a 55-year-old woman in Liverpool, England has admitted to killing her newborn son back in the late 1990s. The body of an infant was found in 1998.

Although the attempt to identify the newborn initially failed, DNA did connect the baby to his living brother. That helped investigators piece together what happened.

Joanne Sharkey confessed in 2023 to killing her son, dubbed Callum, found in bin bags near Gulliver’s World in Warrington. Forensic evidence showed asphyxiation from tissue paper in his mouth. DNA eventually linked Callum to Sharkey’s son, Matthew, leading to her arrest.

A Secret Birth Unraveled

Reportedly, Sharkey hid her pregnancy, gave birth alone, and silenced Callum (not the baby's real name) in panic, later admitting it to her husband, Neil. It's this latter conversation that was pivotal in understanding what happened as it was recorded. Her charge shifted from murder to manslaughter due to postnatal depression. She awaits sentencing with family support.

Why This Case is Important to the True Crime Readers

This case is just one example of many cases where a mother or parent murders a newborn child. This is a scenario that true crime readers need to be familiar with.

I’ve studied many John Doe and Jane Doe cases where it is very clear that the unidentified person is a newborn. The giveaway is that they are often incredibly light, exceptionally short for an estimated height, wrapped, and discarded like Callum. In these cases, I have suspected parental panic, a pattern Sharkey’s story fits perfectly. I'm sure my suspicions in these cases will align with everyone else's.

Here are some other cases that mirror this tragedy, showing a recurring theme of concealment. Below is a small table of examples where mothers killed newborns and hid the remains:

Resolution’s Rarity

I rarely work on these kinds of cases since secret newborns lack missing persons reports. Obviously, if the mother kills her own child, she isn't going to have an interest in reporting her baby missing. I can't think of much of a research angle for such cases.

Identification mainly looks like it will be dependent on, not just forensics, but the police having the time and resources to pursue the investigation. In my opinion, the number of discarded newborns in any nation will be shockingly high.

At the time of writing, if you went to NamUs and searched unidentified remains as either infant or fetus, then you would get 606 results. That is just a small sample, capturing only the cases that end up digitalized. Some of them go back 80 years now, highlighting the unlikelihood of resolution.

Politically, I think the cases relate to the topic of abortion. It's important not to overgeneralize as not all the cases would be related to the topic.
