The fourth victim killed by a suspected serial killer was laid to rest Saturday afternoon. 

Ronald Felton, 60, was a church volunteer who helped serve needy families in the Bay area. 

Funeral services were held at Allen Temple. 

"Even though this tragedy happened, we know that God still had brother Felton in His hands," said Rev. Glenn B. James, Jr. "You know why? Because you could not stop his good deed. You could not stop his loving heart. You could not stop his legacy which shall live on for days to come."

Felton was killed on Nov. 14 as he was walking to volunteer at a food bank on Nebraska Avenue. Police said the suspect came up behind Felton and shot him. 

Officers responded to the area within minutes and closed down the streets in the area, but were unable to find the gunman. 

The suspect was captured on surveillance video moments before Felton was killed. Police said it appears to be the same person seen in surveillance video taken on Oct. 9, minutes before the killer struck for the first time. 

Investigators said this is the most definitive evidence yet that at least two of the killings were committed by the same person. 

Tampa police are keeping a high profile in Seminole Heights and have now added horseback patrols. 

The mounted officers are working several streets near where the four murders occurred. 

The homicides have left residents scared and city officials frustrated because there has not been an arrest despite a reward of more than $100,000.

The department has received around 1,100 tips.

Despite the killer still being at large, Felton's family has faith.

"I know he will be caught," said Linda Cunningham, Felton's sister. "One way or the other. Either man is going to catch him or God is going to take care of him."
