Police say they are determined to unravel the mystery surrounding the death of 40-year-old Longforgan woman Jane Cumming.
Mrs Cumming was found at her home in Mary Findlay Drive on Friday when officers arrived to tell her that a man, believed to be her husband Neil (45), had suffered life-threatening injuries in a serious road accident on the A90 near Dundee.
The incidents are being linked by police and her death is being treated as suspicious.
The spokesman on Monday confirmed the 45-year-old man injured in the collision with a lorry near the Landmark Hotel “is of significant interest to the investigation.”
“He remains unconscious and in a serious condition in hospital today. Officers have not had the opportunity to speak with him as yet.”
Mrs Cumming is also survived by her two daughters, Nicole (12) and Claire (11), who are being cared for by relatives. The spokesman said every effort is being made to support the children.
“Obviously, this is a desperately upsetting time for the family, two young girls in particular, and Tayside Police are offering them all the support we can.
“This is a tragedy for a young family and we are determined to find out what happened,” he pledged.
Perth and Kinross provost and local councillor John Hulbert agreed the community would rally round the family to offer what help and support they could.
Dr Hulbert, himself a Longforgan resident, said the quiet village had been taken aback by the tragedy.
“The community was very, very surprised and devastated,” he said. “It is a terrible tragedy for the family, especially when there are a couple of children involved.
“These things happen everywhere, I suppose, but uncommonly in a village like Longforgan.”
Meanwhile, detectives have been trying to piece together Mrs Cumming’s movements in Longforgan or Dundee during Thursday evening and up to 11.30am on Friday.
Detective Inspector Caroline Lindsay said, “If anyone saw her on foot or travelling by car, we want them to get in touch with us. Jane drove a silver Toyota Yaris, which bears the distinctive private registration number of W2 BJC.”
Police also want to hear from the occupants of a dark blue or black 4×4 vehicle that passed the scene of the collision at around the time that it happened. It is believed that a child in the car may have filmed or taken photographs of the incident on a mobile phone or camera.
“While the driver of that car may have spoken with police officers already, Tayside Police would appeal to them to get in touch,” added the spokesman.
Officers are also keen to speak to anyone who was at a popular playpark that looks into the back of the family home on Friday morning.
Blairgowrie-born Jane worked as a sales adviser at TSB in Dundee’s Albert Street and a spokeswoman for the bank said her colleagues’ thoughts were with her family.
The house was cordoned off to allow a full and meticulous investigation of the scene. A post mortem was held on Monday. As with all sudden deaths, a report will be submitted to the procurator fiscal.
Anyone with information that could assist the police investigation should call 0300 111 2222 or speak to their local officer.
