This comes almost a month after a killer shot and killed three people over the span of 10 days in Seminole Heights.
A massive police presence descended on the neighborhood, and as of 7:30 a.m., many streets had been closed, according to NBC News affiliate WFLA.
Hegarty said that investigators are treating the death as related to the three recent unsolved murders in Seminole Heights. Police patrolling nearby heard the gunshots and rushed to the scene to find Naiboa dead.
Hegarty said the suspect couldn't have "gone very far, and we're talking to as many people as we can to see what they may have seen". Nebraska Avenue is shut down between Hillsborough and Osborne avenues for the investigation.
Benjamin Mitchell, 22, was killed Oct. 9; Monica Hoffa, 32, was killed in a vacant lot Oct. 11; and Anthony Naiboa, 20, was shot and killed Oct. 19.
Last week, Seminole Heights residents returned to some normalcy following last month's murders with a "Taste of the Heights" celebration.
Monica Hoffa, 32, was found dead in a vacant lot on October 13 after being shot. She was shot and killed. Mitchell was shot and later died of the injuries he sustained.
Police have released video of a person of interest running during the night of the first murder.
