Minnesota – A family of four was shot to death while sleeping in their home in Minnesota in what authorities believed to be a ‘murder-suicide’ incident, officials said.

“A family of four, including two children, were fatally shot while sleeping in their Minnesota home in what police believe to be a murder-suicide incident, authorities say,” ABC News Tweeted.

The suspect who was the family’s relative was also found dead at the scene with an alleged self-inflicted gunshot injury, reported Duluth Police Department Chief Mike Tusken.

“It’s just a sad day,” said Tusken who was shaken to the core, during Thursday’s briefing of the crime incident.

“In 32 years, we haven’t seen anything like this, when we’ve had four victims of a homicide,” he added.

After next-of-kin notified the officials, they publicly revealed the victims’ identities; Sean Christopher Barry, 47, Riana Lou Barry, 44, Sadie Lucille Barry, 9 and Shiway Elizabeth Barry, 12.

On Wednesday afternoon, Duluth police ended up at the crime scene in the East Hillside neighborhood after receiving a request for a welfare check in Hermantown, residing close to the Hillside neighborhood, regarding a person suffering from mental health crisis.

A family member also provided the officials with the message that the suspect sent to them and later uploaded on social media, denoting that he intends to harm himself and the rest of the family, said authorities.

As of now, the Hermantown police department is unable to track down the suspect, identified as Brandon Taylor Cole-Skogstad, 29. However, they provided Duluth officials with the suspect’s Duluth home address which is apparently owned by his uncle and aunt, said authorities. Moreover, Duluth police also got to know that the “suspect had access to a weapon’, Tusken said.

During the incident reporting, Duluth police said they heard the sound of a single gunshot when they knocked on the door.

Due to security purposes, officials initially used drones and robots to check the premises, however, the devices couldn’t enter all the rooms, said Tusken.

After a tactical team performed a detailed room-by-room search, they found 4 victims lying dead on their beds with the gunshot wound, including, 2 children and a dog.

“This is a tragedy for Minnesota, a tragedy for, certainly, the city of Duluth and for this community,” Tusken said. He hopes “getting the facts out will provide some closure and healing.”
