Police on Jersey say they are unlikely to launch a murder investigation, despite the partial remains of at least five children having been found at a former care home, because the bones cannot be dated.

The news emerged as a group of MPs met a government representative yesterday about the rule of law on the island, amid allegations of an attempted cover-up.

So far, 65 milk teeth belonging to children aged between four and 11 and more than 100 bone fragments have been found at the former Haut de la Garenne home.

But forensic scientists are unable to put an exact date on them, said deputy chief officer Lenny Harper, who is leading the investigation.

"We were pinning our hopes very much on the process of carbon-dating," Mr Harper told BBC radio.

"The latest information we're getting is that for the period we're looking at, it's not going to be possible to give us an exact time of death.

"The small number of bones that we've had carbon-dated up until now have given us different readings. One bone, we were told there was a probability that the person had died in 1650 but also a smaller probability that they died in 1960."

Mr Harper added: "At the end of the day there just might not be the evidence there to mount a homicide inquiry to bring anybody to justice for whatever crimes took place."

But he said a "number of valuable pieces of evidence" had been unearthed which substantially corroborate accounts of abuse at the home given by victims and witnesses, including DNA samples and shackles.

About 100 people have made allegations of abuse going back as far as the 1950s.

Police said the teeth were in a condition which meant they could only have come out after death, while the bone fragments identified so far included one from a child's leg and another from inside a child's ear.
