The three homicides have prompted fears of a serial killer

"I'm mad because I feel my community has been violated," mayor says

CNN  — 

The mayor of Tampa has a message for police officers hunting down a mystery killer: “Bring me his head on a platter.”

Three people have been killed in the Seminole Heights neighborhood in 11 days, leaving the Florida community terrified that a serial killer is on the loose.

“I’m mad because those three families had a huge hole ripped in their hearts,” Mayor Bob Buckhorn told CNN’s Mike Galanos . “That scumbag who did that, we’re coming for you. I told them (officers), ‘bring me his head on a platter. ‘”

Authorities released new grainy surveillance video this week showing what they described as a person of interest running away from the first of the three homicides.

The grainy surveillance video, taken at different angles, shows the same person who was seen walking along a street in the historic Seminole Heights neighborhood in an earlier video released by police.

“I’ve come up with four reasons why this person is running,” interim Tampa Police Chief Brian Dugan told reporters. “One, they may be late for dinner. Two, they’re out exercising. Three, they heard gunshots and, number four, they just murdered Benjamin Mitchell.”

The victims

Benjamin Mitchell, 22, was shot and killed in front of his home on October 9.

The second victim, Monica Hoffa, 32, was killed October 11. Her body was found two days afterward by a city employee in a vacant parking lot half a mile from where Mitchell died.

Then a week ago, Anthony Naiboa, an autistic 20-year-old who had just graduated from high school, became the third victim after he accidentally got on the wrong bus after leaving work and ended up in the southeast Tampa neighborhood by mistake, police said. Authorities believe he was making his way to another bus stop but did not get more than 200 yards before he was shot and killed October 19.

The three victims were alone and found within about a half-mile of each other, Dugan said.

Police posted a link to the video on Twitter.

‘Ties to the neighborhood’

Dugan said the person in the video is not considered a suspect in the string of shootings that have residents of Seminole Heights on edge.

“He may have seen something or heard something,” the chief said of the person, who is seen flipping what appears to be a cellphone in their right hand while walking.

Any clue, any little detail such as the phone flip, may lead to a break in the case, authorities said.

“That might be a habit of this person,” Dugan said of the phone flip. “At this point, everything is a clue, everything is a speculation.”

In the video, the person is seen walking in one direction, then running the opposite way seconds after Mitchell was shot.

“We believe this person has ties to this neighborhood and we want to speak to them,” Dugan said.

Tampa Mayor Bob Buckhorn said officials don’t have many leads on who is behind the three shootings. Nor do authorities have a motive for the seemingly random acts, he said.

“I’m mad because I feel my community has been violated,” Buckhorn said Thursday. ” I’m mad because these good folks here … many of whom I know, are being held hostage by this person.”

Few clues

Police are asking for clues on the person in this surveillance video.

Police last week released a surveillance video of the same person walking in the area and asked for any information on that person.

Buckhorn said they didn’t have any description of a suspect or suspects and could not even say if the suspect was a man or woman.

“We’re not using the word ‘serial killer’ yet because we just don’t have enough evidence,” Buckhorn said. “We’re not afraid of that word – if we think that that’s true, we’ll be happy to say it. But we’ve got to connect the dots.”

As the investigation goes on, Dugan said there will be a large police presence in Seminole Heights.

The city has cleared alleys, added streetlights and cut undergrowth to ensure visibility
