Minneapolis police on Thursday were searching for the culprit in the shooting death of a 49-year-old man inside his Harrison neighborhood apartment.
The victim, whose name was not released, was found in a ground-floor unit at 1618 Glenwood Avenue N. by officers conducting a welfare check, police said.
Police are waiting for results of an autopsy, expected in the next few days, to determine when the slaying occurred.
The man was found about 9:30 a.m. by officers after his landlord grew concerned and called police, officer Corey Schmidt said Thursday.
Authorities declined to discuss the investigation further, saying it could compromise the probe.
"It would be unfair for me to assume that the victim knew" his assailant, Schmidt told reporters at a midday briefing.
Police wouldn't comment on whether the man was shot inside apartment No. 1 even though the front door was peppered with seven gunshots, according to police scanner traffic.
Several neighbors reported hearing gunshots about 2:30 a.m.
