U.S. Attorney Barbara McQuade says her office will closely monitor the investigation into the fatal shooting of a Detroit man by a federal agent who was part of a fugitive apprehension team seeking him on a warrant.

McQuade said Tuesday that "police work sometimes requires use of deadly force, but officers may use only as much force as is reasonable under the circumstances."

An autopsy shows 20-year-old Terrance Kellom died of multiple gunshot wounds following Monday's confrontation with the U.S. Immigration and Customs Enforcement agent in a west side home.

ICE says Kellom was wanted on armed robbery and weapons charges. State Corrections records list him as a probation absconder.

ICE and Detroit police are separately investigating Kellom's slaying. Neither agency commented Tuesday on the case.
