A depraved killer and necrophiliac who sexually abused more than 100 corpses at Kent hospitals is set to be charged with further offences, it is understood.

Murderer David Fuller was jailed for life last year after pleading guilty to the murders of Wendy Knell, 25, and Caroline Pierce, 20, in two separate attacks in Tunbridge Wells in 1987.

After admitting to beating and strangling the young women, Fuller, 67, also admitted a further 51 offences to abusing at least 102 victims in the mortuaries of Kent and Sussex and Tunbridge Wells hospitals over more than a decade.

Dozens of his victim's identities remain unknown, but his youngest was just nine, while his oldest was 100.

But it was revealed this week the former electrician could be charged with further offences in the coming weeks, according to The Sun.

A source told the newspaper: "It was always expected that there would be more.

"Detectives have worked tirelessly to identify victims and hope to get justice for their families."

It comes after Kent Police revealed in December it would be looking into cases of missing women, rapes or murders in the South East which remain unsolved for any links to Fuller.

Speaking after a harrowing day in court where the depraved killer was sentenced, Det Ch Supt Fortheringham said the investigation could take "at least a year".

He said: "I don't know what I can say to the victims families apart from I cannot imagine what they've gone through.

"My thoughts are always with them, they're the reason why we've continued the investigation and I hope they can get some peace."

He added: "We still don't know what happened to Caroline in those three weeks. We've asked to see David Fuller in prison to ask him to tell us, so that we can tell Caroline's family, but he's refused to do that.

"Because there are three weeks where we don't know what happened to Caroline, and I want to tell the family that, so that they can have some peace, but he's decided not to tell us."

Fuller was sentenced to two whole life orders for the murders of Ms Knell and Ms Pierce, as well as being given concurrent sentences totalling 12 years for the sexual abuse of the deceased females.

He had filmed himself carrying out the attacks inside the hospitals, where he was working in an electrical maintenance role.

Following the horrific incidents an inquiry has been launched to find out exactly how Fuller was able to commit such crimes.

Sir Jonathan Michael was appointed by the Health Secretary Sajid Javid to lead an inquiry into how Fuller could have been able to perpetrate such offensive crimes and for such a long period without discovery, and whether there were safety implications for mortuaries at other hospitals across the country.

Sir Jonathan has faced criticism from lawyers representing some of the abused mortuary victims, who question how fair and independent he can be.

He is a former chief executive of three NHS hospital trusts: Oxford University Hospitals NHS Foundation Trust; Guy’s & St Thomas’ NHS Foundation Trust; and University Hospital Birmingham NHS Foundation Trust.

The inquiry will be in two parts. The first will focus on Fuller’s specific crimes in the Kent and Sussex and the Tunbridge Wells Hospitals.

The second part will be to look at the implications for the country as a whole and make appropriate recommendations "in order to ensure that Fuller’s horrendous activity cannot be repeated elsewhere."

Kent Police were approached for comment but only said there were "no new charges at this stage".
