Police are trying to trace the last known movements of a convicted sex
offender whose mutilated body was found in a shallow grave.
The body of former history teacher Alan Wilson was found on Tuesday
The dismembered remains of Alan Wilson, 51, were found buried in the garden of
an Edinburgh tenement on Tuesday.
The former history teacher was jailed for 18 months in 2000 for abusing three teenage pupils over a five-year period.
It is understood a friend of Mr Wilson's, also a convicted sex offender, lives
nearby and is yet to be questioned.
The gruesome find by police in a communal garden area of Merchiston Avenue has
horrified residents of the affluent suburb.
A post-mortem examination has been carried out on the body, which had been cut up, placed in bin bags and then dumped.
Murder squad detectives believe Mr Wilson's remains were deposited in the garden
some days ago, after he was killed and dismembered at another location.
Police revealed the former teacher had been missing for over a week.
The detective in charge of the case has issued a plea for information
surrounding Mr Wilson's death and his whereabouts in the run-up to the murder.
Det Supt Bert Swanson said: "Alan had probably been dead for a number of days
before his body was discovered.
"We are trying to build up a picture of where he has been, particularly since the start of February."
Divorced father-of-two Mr Wilson lived in Royal Mile Mansions, North Bridge, in
the Scottish capital, where he was caretaker of the building.
A former teacher at James Gillespie's High School, he was jailed in 2000 after
being found guilty of eight sex assaults on three teenage boys between
March 1994 and September 1999.
