ST. PAUL — The reward is now up to $40,000 for a Minneapolis man accused of killing his ex-boyfriend at an Arden Hills gas station a month ago.

The Ramsey County sheriff’s office on Wednesday announced the increased reward for information leading to the arrest and conviction of 44-year-old Lyle “Ty” Hoffman. The reward previously had been up to $25,000.

Hoffman is wanted in the Aug. 11 fatal shooting of his former boyfriend and business partner, Boston Scientific executive Kelly Phillips.

Hoffman is also suspected of robbing a TCF Bank in Blaine on Aug. 30. Authorities say the handgun used in the shooting and the bank robbery has not been recovered.
