Police have sealed off an area in a Florida city where a fourth person has been shot to death, possibly by a serial killer.
Police believe the four killings, none of which involved a robbery or other obvious motive, may be related.
Foot traffic in Seminole Heights dried up, as fear - and additional police - saturated the neighborhood.
Interim Tampa Police Chief Brian Dugan said it is extremely possible that the killer - or killers - live in the neighborhood.
Tampa police said early Tuesday they're investigating a suspicious death in the city's Seminole Heights neighborhood.
"We are going to stay on this until they catch this guy", pledged Tampa mayor Bob Buckhorn.
"We think by their proximity and the manner it was done, they are linked", said Dugan during a news conference on Tuesday morning.
Last week, in a separate case, police arrested a 22-year-old man suspected of killing three homeless men in and around Fort Lauderdale on Florida's Atlantic coast.
Anthony Naiboa, 20, was shot to death October 19 after he accidentally got on the wrong bus after leaving work and ended up in the neighborhood by mistake, police said. They said they are looking for a thin black man, about 6-feet tall, wearing black clothing and carrying a large handgun. Several schools in Hillsborough County were on a lock-in on Tuesday morning.
Any Seminole Heights resident who owns a gun should also verify its location. Drivers are asked to find another route.
The killings began on October 9, when 22-year-old Benjamin Mitchell was shot and killed in front of his home, CNN reported.
"We're saying it's related to the other Seminole Heights murders". He was killed at a bus stop along N. 15th Street and East Frierson Avenue. Two days later, 32-year-old Monica Hoffa, was slain.
"A lot of serial killers prefer other methods such as knives or strangulation", she said.
Tampa police are offering up to $35,000 for information about the slayings.
Surveillance video from on the night of the first murder shows a hooded person of interest walking down the street and checking their phone before stepping out of frame.
