(AP) — A man charged with killing his ex-girlfriend has been arrested in Detroit.

The  24-year Lee Edward Williams is expected to appear before a Michigan judge Monday to determine if he will fight extradition. He is charged in Wyandotte County District Court with first-degree murder in the Sept. 4 shooting death of 20-year-old Ty’Shai Carvin. He is also charged with illegally possessing a firearm.

Authorities also have filed a motion seeking to revoke his probation in a drug distribution case.

Family members said that Williams and Carvin had dated, but she was trying to break off the relationship. Carvin was the mother of a 2-year-old boy.

A $500,000 bond was set in the murder case. It’s not immediately known if Williams has an attorney.
