The trial of one of two Dickson men accused of raping a teenager was delayed until next week while the defense fights to exclude DNA evidence linking him to the assault. The second defendant’s trial has been postponed until February while he undergoes a mental evaluation. 34-year-old Donald Keith “Duck” Watts of Brookside Drive was scheduled to go on trial Wednesday in Dickson County Circuit Court on a single count of rape. Watts and 33-year-old Danuell Maurice Tharpe of Haley Road were both indicted for rape in March for having sex with a teen-aged girl who allegedly was incapacitated due to alcohol consumption at Tharpe’s home in February 2012. With jury selection set to begin, defense attorney Joey Hornick asked Judge David Hayes for a continuance to allow him to file a motion seeking to suppress statements made to police by Watts and the results of a DNA test. Assistant District Attorney Ray Crouch joined in asking for a delay because due to what he called “a slipup,” the defense was not given a copy of Watts’ videotaped interview until Tuesday evening. Hornick wants to argue that the DNA evidence should not be allowed because police obtained a sample from Watts without a warrant and before he was even told he was a suspect in the case or read his rights. “They knew what they were doing, got what they needed and then read him his rights,” Hornick said. “DNA evidence is a tremendous portion of this case.” Hornick said Watts voluntarily went to Dickson police after learning they wanted to talk to him. During the videotaped interview, he is questioned about Tharpe’s alleged actions, asked to provide a DNA swab and then detectives read him his rights and informed Watts he also was a suspect, Hornick said. Crouch said he intends to use the entire videotaped interview as evidence in the prosecution and that Watts’ DNA was matched to a vaginal swab from the 16-year-old victim. Hayes scheduled a hearing on the motion to suppress the DNA evidence for Monday before Judge George Sexton with the trial to start immediately after his ruling. Hayes rescheduled Tharpe’s trial to Feb. 11 to allow time for him to undergo a mental evaluation. Crouch said the victim was forced to have sex with both men while she was under the influence of alcohol at Tharpe’s home. He said the teenager has since moved to Ohio but is in the process of returning to Dickson County to live. When he showed up for his trial Wednesday morning, Watts was arrested on an outstanding warrant for probation violation and sat in handcuffs while his attorney sought a delay.
