A man has been arrested in connection with the recent string of homicides in Tampa's Seminole Heights neighborhood, police announced at a press conference late Tuesday night.
"Tonight is the beginning of when justice will be served," Tampa Mayor Bob Buckhorn said. "And then the process will occur when this individual will rot in hell.
"Tonight we are bringing someone to justice who does not deserve the right to walk among us," Buckhorn continued.
Donaldson, 24, will be charged with four counts of first-degree murder, police said. Authorities said they still have no motive in the murders, however, and police were unsure of his connection to the Seminole Heights neighborhood.
"Chief Dugan credits arrest in series of Seminole Heights murders to hard work of officers, federal partners, and community members," the Tampa Police Department tweeted.
Florida Gov. Rick Scott commended the "relentless effort" of the Tampa police, who worked through the Thanksgiving weekend on the case.
"As a father and a grandfather, it is unimaginable what the families of these victims are going through," Scott said. "Our thoughts and prayers remain with them, and we will work to ensure that they receive the justice they deserve. In Florida, we have absolutely zero tolerance for this type of evil behavior and anyone responsible will be held to the fullest extent of the law."
Tampa police earlier in the day had said they were "optimistic" that a tip that led them to a McDonald's to investigate a person with a gun was connected to the deaths.
Police responded to the McDonald's in Ybor City at 2:45 p.m. after receiving the tip and confronted the person who had the gun, Tampa Police Chief Brian Dugan said in a press conference. They interviewed the individual at police headquarters, but Dugan reminded reporters at the time that he or she could have been "completely innocent."
"We'll see what type of answers this person has for us," Dugan said.
