Fifty-one days and 5,000 tips later, Tampa police said they arrested the man responsible for the four serial killer murders in Seminole Heights.

"We are pleased to announce that tonight we will be making an arrest in the Seminole Heights murders," said Tampa Police Chief Brian Dugan during a late-night news conference.

Howell Emanuel Donaldson III, 24, was arrested after police received a tip from an Ybor City McDonald's Tuesday afternoon.

Police said that one of Donaldson's coworkers approached a police officer to say that he had a firearm in a bag. Once the officer looked inside, he called for backup.

They took Donaldson in for questioning after the gun was recovered from the scene.

Donaldson is accused in the murders of Benjamin Mitchell, Monica Hoffa, Anthony Naiboa and Ronald Felton. They were shot within a half mile of each other. No connection between the victims was ever revealed.

Donaldson will be charged with four counts of first-degree murder.

"I am overjoyed right now. I am shaking right now because like I should be, my hands are sweaty, I am just very joyed that we caught this killer and got him off the streets," said Robert Hoffa, Monica's uncle.
