Police were called to 300 W. 23rd and Rutland Street around 1:30 a.m. after reports of deadly shooting in the Heights.
According to investigators, about six to eight people were at the residence for a party when the shooting occurred.
Authorities say one man decided to put on a bulletproof vest while one of the party-goers fired a shot at him.
"It is unusual that people would put on bulletproof vest and play with guns at a party, but these things happen sometimes," HPD Homicide Sgt. Mark Hollbrook said.
Police are working to locate the person who shot the victim and another male to determine more about the incident.
Investigators are waiting on forensics to determine whether the bullet went through the vest or skipped the panel.
