Jess

You see, it's an offence to abandon a child under two if it endangers their life or causes them harm.

That's punishable by up to five years in prison.

Then there's a broader offence of cruelty to a person under 16, including neglect, ill-treatment or abandonment.

And for that, you could get 10 years.

And because we don't in the UK have a statute of limitations for serious crimes, someone can be prosecuted today for abandoning a baby back in 1987.

This case was never actually solved, so new information, fresh evidence, or a recent forensic technology like DNA could open it up again.

You and I know that we don't want... That's absolutely not the motivation.

Neither of us wants that.

Yet several former police officers seem genuinely concerned that my reporting of this story may have a real life effect, a fresh criminal investigation.

All of a sudden, the stakes feel much higher.

I check in with Jess.

She's still certain that she wants to tell her story and to try and find answers to the questions she's been asking for years.

I write again to all the retired police officers, assuring them that neither Jess nor I are looking to reopen the case, that we're not seeking new evidence.

But they don't change their minds.

Eventually, I find a fourth former police officer.

Initially, he says no, but after thinking it over, he agrees to talk because, he tells me, Jessica deserves some answers.

In his retirement, Oldwyn Jones sits on the committee of a village hall, and so we meet there.

He's a former detective chief inspector at Ipswich Police Station.

He's a tall, polite man with glasses and salt-and-pepper hair.

Babies are abandoned intermittently, but more often than not, it's their lifeless bodies that are later found.
