Bid To Trace Final Movements Of Pair Found Dead
Police investigating the deaths of two sisters-in-law in a Glasgow flat are trying to trace their final movements.
The bodies of Sharon Dodd-Archibald, 46, and Mary Archibald, 51, were found in a flat in Dalserf Court, Gallowgate, at midday on Sunday.
Carbon monoxide poisoning was being investigated as a possible cause of death but tests of the flat's boiler by the Health and Safety Executive and Scottish Gas found no faults, and it is said there are no other gas appliances in the property.
Officers want to speak to anyone who saw or spoke to the women on Saturday or the early hours of Sunday while the results of post-mortem and toxicology tests are awaited.
Police Scotland said the deaths are being treated as unexplained but are not thought to be suspicious.
Detective Inspector Ogilvie Ross said: "As part of the ongoing investigation we are trying to establish their last known movements and I would ask anyone who knew Sharon or Mary, who spoke to them, or saw them on Saturday April 23 or early on Sunday April 24 who have not yet came forward to police to contact us at London Road police office through the non-emergency number 101.''
Homes near the flat were evacuated on Sunday due to the possibility of a gas leak but residents were allowed to return the next day.
