MINNEAPOLIS — The citizen whose tip helped police capture a man suspected of shooting his former boyfriend and business partner to death at an Arden Hills gas station will collect a $40,000 reward.

Lyle “Ty” Hoffman was arrested peacefully in Shakopee after the citizen phoned police to report someone lingering around several retail outlets. Hoffman had been sought for a month following the killing of Kelly Phillips, an attorney and Boston Scientific vice president.

The tipster wants to remain anonymous.

Gary Schiff, a friend of Phillips’ and president of the anti-crime group that helped collect reward donations, said generosity to the fund helped publicize the case and lead to the tip.
