Court documents released Tuesday reveal that Brian Short purchased a shotgun just a day or two before he used it to kill his wife, three children and himself in their home on Lake Minnetonka.
The Hennepin County Medical Examiner has ruled that Short, 45, shot and killed his wife and three teenage children in their Greenwood home before killing himself. They all died of gunshot wounds to the head.
The children were found in their bedrooms, wife Karen was near the master bedroom, and Brian Short was in the garage.
During their search of the property, police found a 12-gauge shotgun near Brian Short's body, along with an owner's manual. They also found a receipt which shows the gun was purchased at a Gander Mountain store in Eden Prairie on Sunday, Sept. 6, according to WCCO.
Police believe the shootings took place Monday or Tuesday. But the bodies were not found until Thursday Sept. 10, after an employee at Short's company alerted authorities that he had not been at work for several days, and his children had missed school, according to the warrant.
The police are also looking at cellphones, computers and other electronics at the family home as they continue their investigation, WCCO reports.
The search warrant doesn't indicate a motive for the shootings. However, one family member who spoke at the family's funeral service on Sunday indicated Brian Short was under stress because his business was having financial difficulties. He also said Short was being treated for depression and anxiety.
