Heilman's Family Wants Justice For Son's Shooting Tyler Heilman was unarmed, wearing a swimsuit, when a cop fatally shot him.

July 22, 2009  -- The family of Tyler Heilman, the 24-year-old Minnesotan who was fatally shot despite being obviously unarmed -- he was wearing only a bathing suit -- wants the officer involved to be "taken down."

Heilman had been driving "erratically" on his way home from a day of swimming at a Minnesota lake Monday when Le Sueur County Sheriff's investigator Todd Waldron approached him and later shot him as many as four times, according to authorities.

"This guy has got to go down," said the dead man's uncle, Patrick Heilman. "He's insane. You don't just gun someone down like that."

Heilman, 45, said that his nephew is survived byhis 3-year-old son Haydin and his girlfriend of seven years. He had been driving to a friend's apartment in the small rural town of Kasota, Minn., about 80 miles southwest of Minneapolis, just before he was confronted by the officer.

"The cop got out of control and lost it. All Tyler had on were swimming trunks," said Heilman.

Kris Hoehn, one of Heilman's best friends who was with him when he was killed, told ABC News' Minnesota affiliate KSTP-TV that his friend had no idea the man confronting him was an officer and that if he had, he would never have argued with him.

The argument escalated into a brawl where the two men ended up wrestling on the ground.

According to police, Waldron approached Heilman, who had exited his vehicle, in
