A pervert pensioner is facing a long jail sentence after he was convicted of sexual abuse of a girl and boy dating back about 40 years.

Father-of-seven Alan Jackson, of Clyde Street, Sheerness, was remanded in custody and will be sentenced next Thursday, October 24.

His sister Cinthia Dungey, of Hollybank Hill, Sittingbourne, was acquitted of all charges against her by the jury of seven women and five men.

Jackson, 67, denied two charges of rape, five of indecent assault, six of indecency with a child and five other serious sexual offences.

He was convicted of two offences of rape, six of indecency with a child and three of indecent assault and cleared of the others.

He had previously been cleared by direction of the judge of two other serious sexual offences and one other indecent assault.

Mrs Dungey, 60, denied two charges of indecent assault and one other serious sexual offence. She had been cleared by direction of the judge of one other charge of indecent assault and three other serious sexual offences.

Maidstone Crown Court heard the victims were not only molested they were also forced to have sex together.

The girl - now a woman in her mid-40s - claimed Jackson on one occasion drowned puppies in front of her and when she begged him to save at least one of them he told her he would if she performed a sex act on him.

She did so, she said, but Jackson killed the puppy anyway, submerging it in water and then stamping on it.

During the trial it was revealed that Jackson had indecently exposed himself several times and committed another sexual offence around the time he was abusing the girl and boy.

His previous convictions between 1970 and 1982, including an indecent assault on a boy in 1973, were read out to the jury.

Jackson said in evidence of those offences: “I had an emotional breakdown.”

Denying the allegations against him, he said of the woman in the latest case: “I would describe her as evil, dangerous, a psychopath, a total liar.”

"Clearly, it will be a lengthy sentence. He has always known what he might be looking at” - Judge Philip St John-Stevens

Catherine Donnelly, defending, asked that Jackson be sentenced immediately but Judge Philip St John-Stevens said he wanted time to reflect on the matter.

“It is going to be a significant term of imprisonment,” he said. “The starting point is 15 years. There is a range either side of that.”

Miss Donnelly said Jackson had a number of health problems, including tinnitus, glaucoma, asthma and a significant heart problem. He had told the court he only had half a lung.

“He has been prepared for this outcome,” said Miss Donnelly. “Clearly, the jury found to some degree in his favour.

"Clearly, it will be a lengthy sentence. He has always known what he might be looking at.”

Judge St John-Stevens said he was adjourning because he wanted to be sure he passed the right sentence.
