THE jury in the Lynda Spence murder trial has failed to reach a verdict after a second day of deliberations.

Colin Coats and Philip Wade, both 42, deny abducting, torturing and murdering the missing financial adviser who was last seen in Glasgow in April 2011.

Jurors at the High Court in Glasgow retired to begin their deliberations at 12.30pm on Tuesday and were sent out again by trial judge Lord Pentland shortly after 10am yesterday.

He told them it is of the "utmost importance" that they do not feel they are under any time constraint. They were released for the day about 4pm, and were due to resume today.

Prosecutors claim the two men cut off 27-year-old Ms Spence's thumb, burned her hand with an iron and hit her with a golf club.

The sentencing of two men who admitted guarding the woman was also deferred.

David Parker, 38, and Paul Smith, 47, pleaded guilty to assaulting her with a golf club, burning her hand, cutting off her thumb and failing to get medical help.

Parker and Smith were also originally charged with Ms Spence's murder but were cleared after pleading guilty to a reduced charge of assault and holding the woman against her will.

It is alleged that friends Coats and Wade abducted Ms Spence on April 14, 2011 and taped her to a chair in an attic at Parker's flat in West Kilbride, Ayrshire.

They held her there for a fortnight as they tried to force her to reveal details of financial deals, prosecutors claim.
