Emergency crews were dispatched around 8:05 p.m. to the area of West Appleton Avenue, south of Hampton Avenue and east of 84th Street, after reports of gunfire, according to the Milwaukee Fire Department.

One person was pronounced dead at the scene. A second person was taken to a nearby hospital for treatment. The fire department did not release the conditions of the injured person, and no information about the identities of either individual was immediately available.

No arrests or suspect information had been announced as of Tuesday night. It was not clear what led to the shooting or whether investigators believe the people involved knew one another.

The location sits along a busy commercial corridor on the city's far northwest side, a short distance from Lawrence J. Timmerman Airport and its surrounding industrial and residential blocks. The area is patrolled by Milwaukee police, who had not issued a public statement on the case by late Tuesday.

Anyone with information about the shooting is urged to contact Milwaukee police or to submit an anonymous tip through Crime Stoppers.

The investigation is ongoing.
