"As part of a responsible investigation into his death, we're looking into the circumstances surrounding it," River Falls Police Chief Roger Leque said.
Chief Leque said investigators are looking into how Bobby Sontag got the alcohol, and are "not pointing any fingers" at this time.
Sontag, a Shafer, Minn. native, was last seen on the 400 Block of South Main Street at approximately 2 a.m. on Friday, May 1. According to police, he was walking home with a friend from the bar and alcohol was believed to be involved. While walking home, the two were separated and the friend went on his own way.
