FLORIDA (CNN)–Tampa Police Chief Brian Dugan said Howell Donaldson III, the suspect charged with killing four people in the city’s Seminole Heights neighborhood, seemed “fine” and knew where he was and what was going on during his interview with police.
“He was friendly and nice to the cops, but he didn’t give us anything, tell us why he was doing it or anything like that,” Dugan said.
 Dugan said that police recovered a hoodie and a jacket from Donaldson that might be the same ones worn by the suspect in surveillance video released last month. More lab work is needed on that, but “it’s encouraging,” Dugan said.
Authorities said the same gun was used in all four killings in the Seminole Heights neighborhood of Tampa, so when police discovered that weapon on Tuesday, they knew they had something to go on.
The suspect, Howell Donaldson III, admitted that he owned the gun, Dugan said. Donaldson was cooperative but did not tell police why he was doing this, Dugan added.
Mayor Bob Buckhorn said he was proud of city, which “has now spent the last 51 days dealing with a serial killer.”
