TAMPA (AP) Police have sealed off a neighborhood where a fourth person has been shot to death, possibly by a serial killer.
Tampa police say they immediately set up a perimeter Tuesday morning around the Seminole Heights neighborhood after finding the body of 60-year-old Ronald Felton.
They say Felton was crossing the street to meet someone when a gunman came up behind him and shot him.
Spokesman Steve Hegarty said detectives can't immediately say whether the shooting is related to last month's killings where three people were slain during a 10-day span.
All three were alone and had gotten off a bus when they were gunned downed at night for no apparent reason. None were robbed.
Police have been boosting patrols in the area. They have released surveillance videos of a hooded suspect after the earlier shootings.
