Action News met with former FBI agent and currant USF staff member Brynna Fox in Seminole Heights, a historic area and now a neighborhood people around the country are talking about.
There have been three murders within weeks and blocks of each other.
"This is extremely unusual to see these murders in this close of succession," said Fox.
Seminole Heights killer: What we know about the 3 murders Tampa police say are linked
Tampa Police believe the killings are linked and while they have not called this the work of a serial killer, Fox, a former FBI agent said according to agency standards anytime there are more than two murders, they approach it as the work of serial murderer.
"It seems to me this is a male offender," said Fox
But Fox is not ready to identify race. She thinks the killer is between 21-35 and either a former or current resident
"He seems that he is very comfortable, very familiar with the area," said Fox.
And she said likely not a person on police's radar.
"It is very rare, most serial killers do not have a long record of offending but what you do see are anti social behaviors," said Fox.
And Fox thinks he's angry.
"He is perceiving a pattern on injustices against him. He may have been laid off work, had a girlfriend break up with him.
He feels the world is against him and he is acting out
And in a mystifying way. Fox said there are three unique aspects not typically seen:
"There's no no sexual element. A gun is the weapon of choice and all three people killed were victims of opportunity.
"That is the most extraordinary thing about this case," said Fox.
For most serial killers the biggest pleasure they get out of it, and the motivation of the offense is typically in the planning. They enjoy the thought of who they are going to victimize and what they are going to do.
Fox also believes he might strike again.
"I would say typically serial killers have an urge to keep offending," said Fox.
But she also said they make mistakes and with all the police focus detectives need just one break to catch him.
Anyone with information about the killings or about the suspect should call Tampa Police at 813-231-6130. Crime Stoppers and the Bureau of Alcohol, Tobacco, Firearms and Explosives have put together a $25,000 reward for any information that leads to an arrest.
