The Hillsborough County Sheriff's Office says a Tampa man now faces second degree murder charges in the death of his father.
Deputies say, on March 27, Shendrick Partin struck his father several times with a hammer and a door stop while the older man lay in bed.
The attack occurred in the 1900 block of Erin Brooke Drive.
Samuel Partin, 61, died from his injuries.
Deputies say they found blood-stained boots, jeans and a sweatshirt during a search after the crime.
They say witnesses saw the son in those clothes on the day of the attack.
Deputies also say they recovered the hammer and door stop with blood on them.
An autopsy found Samuel Partin died from blunt impact to the head with cerebral contusions and lacerations.
The Sheriff's Office says the Florida Department of Law Enforcement discovered the sweatshirt contained both the son's blood and the father's blood.
The FDLE also said the blood on the hammer and door stop matched the victim's blood.
Shendrick Partin remains in the Hillsborough County jail on violation of probation charges.
