Facts of the Crime:
Samuel Smithers was convicted and sentenced to death for the murders of Cristy Cowan and Denise Roach. In 1995, Smithers made an agreement with Marion Whitehurst, who he had met through church, to maintain the lawn at her vacant Plant City house, which sat on 27 acres of land. Whitehurst gave Smithers a key to the gate but not one to the house. In 1996, Smithers again agreed to take care of the lawn at the Whitehurst’s vacant property.
On May 28, 1996, Whitehurst stopped by the Plant City house and found Smithers cleaning an axe on the carport, which he said he had been using to cut down tree limbs. She also noticed a pool of blood on the carport, which Smithers speculated might have been made by someone killing an animal. Smithers told Whitehurst that he would clean up the blood. Whitehurst was disturbed by the blood and contacted the local Sheriff’s Department. Later that evening, a deputy visited the Whitehurst’s property. The pool of blood was gone, but the deputy noted drag marks that went from the carport to one of the ponds on the property. Upon arriving at the pond, the deputy found the body of Cristy Cowan floating in the water. A dive team was called in and found the body of Denise Roach in the same pond.
Officers searched the Whitehurst residence and accumulated evidence against the defendant. They found a condom wrapper and a semen stain in one of the bedrooms. Officers also found Smithers' fingerprint in the kitchen. Using DNA testing, the blood in the carport was found to match Roach’s DNA. Additionally, Smithers and Cowan were seen together on a convenience store security camera tape on the day of Cowan’s murder. The state also determined that both Cowan and Roach were prostitutes who worked the same area, and Bonnie Kruse, another prostitute who worked that area, recognized Smithers as a previous customer. Another prostitute claimed that she gave Cowan a condom on the day that she disappeared, which was similar to the condom wrapper found inside the Whitehurst property.
Two detectives visited Smithers’ home. Smithers agreed to go with them to the sheriff’s office for questioning and requested that his wife join them. At the conclusion of the interview, Smithers consented to take a polygraph test the next day. According to the polygraph test results, Smithers was not telling the truth. A detective explained this to Smithers and then Smithers made incriminating remarks about his involvement in the murders. Smithers again requested that his wife be present during the questioning.
Smithers subsequently confessed to the killings of both Cristy Cowan and Denise Roach. According to Smithers, he was mowing the grass on the Whitehurst property on May 7, 1996 when Roach approached him. Roach explained that she had permission to be on the property. On May 13, 1996, Smithers said that Roach was still there, and he asked her to leave but she refused. Smithers told the officers that Roach hit him on the arm and that he then hit her in the face. Roach picked up a planter on the carport and threw it at his truck. At this point, Smithers shoved her against a wall causing a piece of wood to fall off of a shelf and hit her on the head knocking her unconscious. Smithers left the property but returned the following day and moved her body to the pond.
According to the medical examiner, Roach’s body was very decomposed and had probably been in the water for seven to ten days. She had 16 puncture wounds to her skull, fractures to her face and skull and injuries consistent with manual strangulation. The medical examiner also noted two large slits in Roach’s clothing caused by a sharp instrument. The medical examiner determined that Roach died from the combination of strangulation, puncture wounds and blunt trauma to the head.
In regard to the Cowan murder, Smithers told police that he stopped to help a car that was pulled off to the side of the road. The driver was Cowan. Smithers drove her to a nearby convenience store. When they were getting back into Smithers’ vehicle, Cowan demanded money or she would accuse him of rape. He took Cowan to the Whitehurst residence and gave her all his money, but she was not pleased and threw a drink at him. Smithers reacted by picking up an axe and hitting Cowan in the head knocking her unconscious. Smithers dragged her to the pond. He was cleaning the axe on the carport when Whitehurst arrived. Smithers claimed that he could hear Cowan making noise while he spoke with Whitehurst. After Whitehurst left, Smithers returned to Cowan and hit her in the head again to make her be quiet and threw tree limbs at her.
According to the medical examiner, Cowan had been dead a few hours when her body was found and had probably been alive when put in the water. She had injuries to her eye and lip. In addition, Cowan sustained blunt trauma to her jaw and chop wounds to the top of her head and behind her ear. Furthermore, Cowan had injuries consistent with manual strangulation. The medical examiner determined that Cowan died from the combination of strangulation and chop wounds.
During the trial, Smithers offered different testimony. Smithers claimed that he lied to detectives because he feared that his family would be harmed. According to this testimony, a girl by the name of Mimi was performing community service as a requirement of her probation at the church where Smithers was a deacon. Mimi was not able to complete her hours and offered to have sex with Smithers if he would alter her community service hours, and Smithers agreed. Several weeks later, Smithers was approached by an unknown man wanting to use the Whitehurst property as a location for a drug deal in exchange for not revealing the deal that Smithers made with Mimi. Smithers agreed and allowed the unknown man to use the property. He further testified that he witnessed the unidentified man kill Cowan and Roach.
Smithers was sentenced to death in Hillsborough County on June 25, 1999.
