TAMPA, Florida - Tampa police said Tuesday night they had arrested a 24-year-old man and that he would be charged with murder in four shooting deaths in the Seminole Heights neighborhood that had stoked fears of a serial killer in the area. 

Howell Emanuel Donaldson III, 24, will be charged with four counts of first degree murder in the killings of Benjamin Edward Mitchell, Monica Caridad Hoffa, Anthony Naiboa and Ronald Felton, Tampa police chief Brian Dugan said in a press conference Tuesday.

Donaldson was taken into custody Tuesday afternoon at a McDonald's after another employee said he handed a gun to a manager, who then reached out to an officer in the building, CBS affiliate WTSP reports. 

"When I think I found out there was a gun, and when we looked at his description, it was a little ore than what we really had," Dugan said. "It just felt right. I kinda had a feeling that we were going to get a break."

Investigators are still determining Donaldson's connection to the neighborhood, Dugan said.

"We're not sure why he was in this neighborhood," he said. "We're not aware what he ties are and we don't know what his motive is. But there is a lot more to go."

Police have been searching for the person - or people - responsible for shooting and killing four in the Seminole Heights neighborhood since October 9. Police have said the shootings happened within close proximity to one another, aren't robberies and could be the work of a serial killer. 

Police had increased patrols in the neighborhood and released surveillance videos of a hooded suspect. In a security video taken moments after 22-year-old Benjamin Mitchell became the first victim on October 9, the suspect is running from the scene.  

"I've come up with four reasons why this person is running," Dugan said last month. "One, they may be late for dinner. Two, they're out exercising. Three, they heard gunshots. And number four, they just murdered Benjamin Mitchell."

Two days after Mitchell was shot, Monica Hoffa, 32, was gunned down. And on Oct. 19, Anthony Naiboa, 20, was shot after taking the wrong bus home from his new job. Police patrolling nearby heard the gunshots and rushed to the scene to find Naiboa dead.

Police found the body of Ronald Felton, 60, in the street on November 14.  Police said Felton had been walking across the street to meet someone when the gunman came up behind him and fired.   

Seminole Heights is a working-class neighborhood northeast of downtown Tampa that's slowly becoming gentrified. Run-down homes sit next to renovated, historic bungalows, and trendy restaurants have sprung up near auto body shops.
