Hillsborough sheriff's deputies have arrested the man they believe killed a homeless couple.

The Tampa Bay Times reports 46-year-old Ricky Fitzgerald Hathorn was arrested Monday on charges of murder and sexual battery.

Officials say Hathorn killed 52-year-old Tommy Skeens and his girlfriend 45-year-old Lara Kuchar early Saturday. Detectives believe Hathorn had made sexual advances toward Kuchar. When they died, detectives say Kuchar was partially undressed and beaten. Officials also discovered a blood-covered piece of wood and a used condom nearby.

According to officials, Hathorn admitted to beating the couple.

He was held Tuesday on $550,000 bail. It isn't clear if he has an attorney.
