Raul Serrano, 28, is charged with first-degree murder in the death of 49-year-old Lacy Michelle Woolridge, who partially clothed body was found in the 3100 block of State Road 84 Saturday, according to the Broward Sheriff's Office.
Medical examiners said Woolridge had been dead for a period of time and had a broken neck.
Serrano, a truck driver with Prime Incorporated, claimed he had picked up four different women in Miami-Dade and Broward in the 24-hours before he spoke with investigators after his arrest Sunday.
According to an arrest report, Serrano said two of the four women were prostitutes he had sex with in his truck.
Although Serrano told detectives he did not know Woolridge, her purse and her cell phone were found inside his semi-truck, BSO said.
According to the arrest report, blood was found on the floor mats of the cab of Serrano's truck.
Serrano was questioned by detectives but when they left to work on a search warrant for his truck, Serrano tried to hang himself with his belt in the interview room, the report said.
He also beat his head against the table in the interview room, the report said. He was hospitalized for his injuries but made his first appearance in bond court Tuesday morning.
