MINNEAPOLIS (WCCO) — The Hennepin County Medical Examiner has ruled the May shooting death of an Aitkin teen as a homicide — and police say the boy’s father is the one who pulled the trigger.

The Aitkin County Sheriff’s Office says Dawson Vanportfliet suffered a neck and head wound when his father shot him with a .40 caliber Sig Sauer pistol on May 31.

Vanportfliet died four days later at Hennepin County Medical Center.

Vanportfliet’s death was ruled a homicide, but investigators believe the shooting was accidental.
