The search of the garden where the bodies of Dinah McNicol and Vicky Hamilton were found in November 2007

Convicted killer Peter Tobin has been found guilty of murdering 18-year-old Dinah McNicol.

Tobin, who is already serving a life sentence for the murder of Vicky Hamilton, denied the charge.

Dinah vanished on her way home from a music festival in 1991.

Her body - and that of 15-year-old Vicky - were found buried in the garden of his former house in Margate in November 2007.

A jury at Chelmsford Crown Court took just 15 minutes to find him guilty on Wednesday after a three-day trial.

Tobin, 63, from Johnstone, Renfrewshire was convicted last year of Vicky Hamilton's murder. She had disappeared from a bus stop at Bathgate, near Edinburgh in 1991.

He has also previously been convicted of the murder of Polish student Angelika Kluk.

Tobin's ex-wife Cathy Wilson suffered domestic violence at his hands, but says she never imagined him doing something like this.

She said: "He wasn't like that to me at all. He was just an abusive husband, I don't want to ever belittle that, but that was all he was to me. That was my choice, my stupid choice to stay there too long."

David Martin used to live next door to Tobin and described a man who always appeared to be a good neighbour. He said: "He was quiet, he didnt play loud music. At the time I was out of work and we spent a lot of time chatting on the door step."
