South Bend police are investigating a deadly stabbing Tuesday morning.

Police were called to the 500 block of South Carroll Street at about 4 a.m. Tuesday, according to WSBT.

Officers found a black man dead inside an apartment in the building, which is a former home broken up into three apartments.

Police have not named any suspects yet. However, two men and women that live in the apartments have a good idea what happened, according to police.

Tuesday afternoon, Metro Homicide officials now believe it’s not a home invasion, though it was investigated as one at first.
