Tampa Police Chief Brian Dugan said police have received about 450 tips since the latest homicide in Seminole Heights.

Dugan showed reporters a new video at a Wednesday news conference and said the person has gone from being a "person of interest" to a "suspect." The video, from Nov. 14, showed the black man walking around in a hooded jacket.

According to police, Ronnie Felton, 60, got off his bus stop shortly before 5 a.m. Tuesday and was headed to his church to help feed the homeless when he was shot and killed.

Tampa Police released this video Wednesday.

Felton's body was found at North Nebraska Avenue and East McBerry Street.

"Someone has to know who this individual is. We are now calling this person a suspect, and we need to know who this person is," Dugan said.

The reward for information leading to an arrest in the slayings is now $91,000, Dugan said.

Police are avoiding calling the suspect a serial killer because, while they are convinced the person was involved in two homicides, they're not convinced he was involved in all four.

The person in the video shown Wednesday, according to police, showed many of the same characteristics as the person in a video released Oct. 26.  

Tampa police are trying to calm neighborhood fears while tracking down the killer. Foot traffic was light in the area Wednesday morning as police continued patrols in the area. Authorities did set up temporary cameras in the area overnight.

A perimeter was set up in the area and effectively locked down all day Tuesday before reopening last night. 

Felton's brother, James Felton, asked residents to keep coming forward with information. He got to the scene moments after his brother was shot but police held him back for his own good.

"That soul, he has is nothing but the devil," James Felton said of the shooter. "He just has no kind of morals, no kind of care.  When you take somebody else's soul, he don't care about himself."

Roger Faucher of Seminole Heights said he understands the need for officers to go door-to-door and in some cases go inside.

"Everybody feels the same way," he said. "Always looking over your shoulder. The last guy was shot from behind. Everybody's walking on eggshells. (I'll) be glad when that guy's in custody."

Resident Rylisha Hicks lives next to the bus stop where the first victim was killed. She said she doesn't feel safe on the porch, yet she won't give into fear.

"Everybody is doing what they can, watching out for each other," Hicks said. "They just need that right tip in order to get this person caught."

With such a heavy police presence, arrests in Seminole Heights have doubled from this time last year.

Dugan described the possible suspect as a black man with a thin build who was dressed in all black and wearing a baseball cap. 

Tampa Police are being assisted by FBI agents, the FDLE and Hillsborough County Sheriff's deputies.

Dugan said authorities believe whoever is responsible for the murders lives in Seminole Heights, which may explain why they have been able to disappear so quickly. 

Police continue to work with the community to make sure surveillance cameras are on and recording at all times.
