A convicted killer has admitted murdering a vulnerable woman then chopping up her body.

Andrew Wallace attacked Julie Reilly at her flat in Glasgow's Govan last February.

The 47 year-old gran – who recently suffered a brain injury – had been reported missing by worried relatives who had not heard from her for weeks.

But, a murder hunt was launched last April following the gruesome discovery of body parts close to Julie's home.

Wallace was soon arrested after detectives stepped up the probe.

The 42 year-old thug was due to stand trial this week at the High Court in Glasgow.

But, his QC Ian Duguid told a hearing that Wallace now wanted to plead guilty to the murder of tragic Julie.

Wallace also admitted attempting to defeat the ends of justice by then dumping Julie's severed remains.

Judge Lady Rae was told Wallace was found guilty of culpable homicide in 1992, aged 15.

Wallace now faces life in jail when he returns to the dock later this month.

No further details on Julie's murder were revealed but prosecutors state Wallace assaulted her “by means unknown” and did “inflict violence on her”.

The killing occurred at her home in the city's Shieldhall Road between February 6 and 15 last year.

Wallace then got rid of the body and tried to hide his involvement in the death over a near seven week period.

The charge states at a number of addresses he did “dismember” Julie and cut off her legs with a knife.

He then put the remains in plastic bags and suitcases before burying them at a property in nearby Drumoyne Drive.

Wallace also cleaned Julie's blood stained flat to try and wipe any evidence.

The sick killer went on to tell other people Julie had moved to a new home in Penilee.

Lady Rae remanded Wallace in custody.
