TAMPA — Authorities arrested three more men on murder charges in connection with last week's armed robbery and house fire that left a South Tampa man dead.
Shadow Allen Hill, 20, and Tyler Patrick Robertson, 19, were arrested early Tuesday at Sky Inn, a hotel at 2450 U.S. 92 in Polk County.
Chase Morgan, 17, was arrested at his mother's house at 104 11th St. SE in Winter Haven late Monday.
Authorities had originally suspected four men in the robbery and murder of Richard Lee Blackman, 65, but homicide detectives identified a fifth during their investigation, officials said.
The three overnight arrests followed those of Kermit Lee Sanford, 34, who was arrested Saturday in Polk County, and Tanner Blake Harrison, 19, who was arrested Sunday in Orange County.
Police say the men entered Blackman's home at 6709 Interbay Blvd. early Thursday and attacked him, stole items and set the house on fire.
It is believed that one of the men knew Blackman, but police declined to specify who or release the nature of their relationship.
Firefighters found Blackman downstairs in the living room and pulled him from the burning home. He was taken to Tampa General Hospital, where he died.
All the men are being held in Polk County without bond. Morgan, who is a minor, remains at Polk County Juvenile Assessment Center without bond.
Detectives conducted a search Tuesday morning at the motel where Robertson and Hill had been staying.
Several tips from the community led investigators to the suspects, police said.
