Bay News 9 spoke to a USF criminology professor to get some insight into the Seminole Heights serial killer case. 

A USF criminology professor said some serial killers look completely normal from the outside. 

Ted Bundy, for example, was a law school graduate who was up for Lieutenant Governor and turned out to be one of the most notorious serial killers of all time. 

USF Professor Doctor Bryanna Fox, who worked for the FBI developing criminal profiles, said she is surprised to learn that accused serial killer Howell Donaldson did not live in the Seminole Heights area. 

"The unusual thing in this case that we're hearing right now is that he didn't have any ties to Seminole Heights. That he didn't live there. That is extremely unusual. While we do see that killers may travel to commit their crimes, they typically keep traveling. They don't keep going back to the same place if it holds no value or meaning to them," Fox said. 

Doctor Fox believes police will uncover some type of connection between Donaldson and why he allegedly chose to target Seminole Heights. Fox also said triggers for other killers she has studied can be something immediate like the loss of a job or girlfriend. 

Another thing that can happen is a series of smaller things that cause the trigger. For example, she said if the suspect felt he wasn't getting the respect or opportunities that he deserved. 

"He did go to college. He was playing basketball. He was maybe hoping to have this good job or be on the NBA team and if he didn't get that he might have felt like society did him wrong," Fox said. 

Donaldson lives in the Town N Country area. Police said they are still investigating the suspected killer's connection to Seminole Heights.
