MINNEAPOLIS — A Minneapolis man who pleaded guilty to fatally shooting his ex-boyfriend and business partner at an Arden Hills gas station last summer is now charged with armed bank robbery.

Lyle “Ty” Hoffman was sentenced earlier this year to more than 25 years in state prison for the Aug. 11 death of 48-year-old Kelly Phillips, an attorney for medical device maker Boston Scientific.

Federal charges filed Friday say that on Aug. 31 — while he was on the run — Hoffman used a gun to demand about $20,000 from a bank teller at a TCF Bank in Blaine. The armed bank robbery charge was filed by information, which usually indicates the defendant will plead guilty.

It was not immediately clear if Hoffman had an attorney to comment on the federal charges.
