VALRICO — In March, deputies discovered a dead man in a bedroom while investigating what appeared to be a burglary.
On Monday, authorities charged one of the man's sons with second-degree murder.
They say 23-year-old Shedrick Partin beat his father on the head with a hammer and a doorstop while the man was in bed.
Samuel Lee Partin, 61, died from the injuries, which deputies say were so extensive they needed to use fingerprints to confirm his identity. Deputies say they don't have a motive. They discovered Samuel Partin's body on March 27, when they arrived at 1915 Erin Brook Drive to investigate a reported burglary.
Samuel's wife, Linda Partin, saw broken glass on the floor of their two-story home when she arrived with Shedrick's older brother. She thought the home had been burglarized and called 911.
But detectives found the body and quickly determined a burglary hadn't taken place. They said at the time they believed the crime wasn't random and that the victim knew his attacker.
The couple lived in the Brentwood Hills house with Shedrick Partin, said Hillsborough County Sheriff's Office spokeswoman Debbie Carter.
Though authorities didn't name a suspect, they arrested Shedrick Partin that day, March 27, on charges of violating his probation for previous burglary and grand theft convictions.
While he remained in jail, detectives investigated. They got a search warrant and went through the Valrico home, finding bloodstains. The bloodstains on clothes worn by the son and weapons matched Samuel Partin's DNA profile, according to state analysts, and an autopsy determined Samuel Partin died of blunt trauma to the head. Shedrick Partin is being held without bail. He has been arrested 20 times since he was 15 and has been convicted of grand theft motor vehicle, burglary, petty theft, and obstructing an officer without violence, according to state records.
