A man and woman who died after a disturbance had been at a vigil for a young relative who went missing after falling off a cliff.

It is understood that David Sorrie and Julie McCash had gathered at Drumlanrig Drive in Dundee for 18-year-old Ralphie Smith, who remains missing after falling from Arbroath Cliffs on Saturday.

Mr Sorrie, 32, and Ms McCash, 43, were found dead on the street early on Sunday, sparking a major police investigation.

On Monday, Robert Stratton appeared at Dundee Sheriff Court accused of murdering the pair.

The 42-year-old faced a further charge of attempting to murder Wendy McKinney during the incident as well as assaulting his partner Lee Kinney on various occasions that day.

He is accused of repeatedly seized Ms Kinney by the body, pushing and pulling her, pushing her against a wall, seizing her neck, throwing her to the ground, picking her up and carrying her away all to her injury.

Stratton is alleged to have murdered Ms McCash by striking her on the body with a knife.

He is charged with attempting to murder Ms McKinney by running towards her while brandishing two knives and attempting to strike her on the body with the weapons.

Stratton is accused of murdering Mr Sorrie by running towards him and striking him on the body with knives.

Solicitor advocate Jim Laverty, for Stratton, made no motion for bail during a brief hearing.

Sheriff Lorna Drummond QC continued the case for further examination and remanded Stratton in custody meantime.

He is expected to appear in court again next week.

A large cordon was erected at Drumlanrig Drive to allow forensic investigations to take place after the incident on Sunday.

Officers have moved to reassure local residents that the incident was "isolated".

Detective inspector Brian Geddes, of Police Scotland's major investigation team, said: "Thank you to the members of the public who have assisted us with the investigation - your support is appreciated."

Mr Smith is believed to have fallen at around 1pm on Saturday after going for a walk with his family.

His disappearance sparked a major search involving a helicopter, lifeboats and rescue teams.

Chief Inspector David McIntosh said: "We have carried out extensive multi-agency searches of the coastline for Ralph over the weekend and these will continue today, with support from the Police Scotland Air Support Unit and specialist Police Scotland Search Teams.

"On Saturday, Ralph was wearing a blue jacket, blue jeans and blue and red trainers and he is described as being 5ft 10in to 6ft, with short light brown hair and blue eyes.
