Sharkey fire murders: People in CCTV images traced
Police investigating a triple murder in Helensburgh have traced a man and car seen in CCTV images near the scene.
Thomas Sharkey, 21, and his eight-year-old sister Bridget died following a deliberate fire at their home on 24 July. Their father Thomas, 55, died six days later.
On Friday detectives issued CCTV pictures of two men and blue Renault Clio they were keen to identify.
One of the men and the occupants of the car have now been traced.
Police had previously said they may be "potential key witnesses".
Det Supt Peter McPike said: "As a result of the recent release of CCTV footage and our appeal for information in relation to the identities of the people and occupants of the vehicle we can confirm that we have traced the male seen walking in West Clyde Street, Helensburgh, and the occupants of the blue Renault Clio.
"This has assisted the investigation considerably.
"I can also confirm that I have still not been able to identify the figure in the hooded top and would appeal to that person or to anyone that knows or suspects who that person may be to come forward and to contact the police."
The only survivor of the blaze was 46-year-old Angela Sharkey.
The fire at the family home in Helensburgh's Scott Court broke out at about 05:00 on 24 July.
Police and family members have made several appeals for information, but so far no-one has been arrested over the murders.
The person police are still keen to trace was seen walking north in John Street, away from the direction of the waterfront crossing at West Princes Street, Helensburgh, at about 05:00 on 24 July.
