A man who murdered a grandmother and concealed her body under the floorboards of his flat for more than four years was jailed for life today.

Robert Kelly, 32, was told at the High Court in Glasgow that he must serve at least 15 years behind bars before being allowed to apply for parole.

Kelly pleaded guilty in May this year to murdering money collector Agnes "Nessa" Mechan, 64, by strangling her in Jamieson Street, Glasgow, on August 30, 2002.

He also admitted robbing her of a handbag and £340 cash in the same incident.

Mrs Mechan disappeared after leaving to visit clients in the Govanhill area of Glasgow at 6.30pm on August 30, 2002.

When she went to the flat of Kelly, one of her customers, he attacked her.

He strangled her then dumped her body under the floorboards and covered it with soil.

The court heard that on the day before the murder Kelly told his partner that he was going to mug Mrs Mechan.

Then on the day of the murder Kelly told his partner that he was going to kill Mrs Mechan and showed her the cord he would use to strangle her with.

He then described how he was going to bury the body under the floorboards.

Later that evening he told his partner: "I did it."

Mrs Mechan's body was eventually found in January this year after his partner told a friend who informed the police.

Forensic officers sealed off Mr Kelly's flat in Jamieson Street, and uncovered Mrs Mechan's body on January 24, 2007.
