William Wheeler, 50, pleaded not guilty to manslaughter and felony leaving the scene of an accident charges at his arraignment hearing today. Fourth District Judge Deborah Bail scheduled Wheeler?s jury trial to begin July 18. Donna Franks, 40, died as a result of massive blunt force trauma after falling off the back of a motorcycle driven by Wheeler around 7:22 p.m. March 9. Witnesses said a semi-truck hit the woman after she fell; the Ada County coroner said her injuries were consistent with that description. Idaho State Police investigators have not been able to find the driver of the truck, however, spokesman Rick Ohnsman said today. Idaho State Police say Wheeler; who witnesses say was driving erratically prior to the accident, sped away from the scene shortly after Franks fell off his motorcycle. ISP Investigators also say alcohol is suspected to be a factor in the accident. Franks was not wearing a helmet when she fell off the Saxon single-seat chopper, which had a rear seat retrofitted to the back with suction cups, according to ISP reports. If convicted of manslaughter, it would be the second such conviction for Wheeler, who served almost eight years in Idaho prisons after a 1984 conviction for second-degree murder ? a charge that was changed to voluntary manslaughter in 1992 after a judge ordered a new jury trial for Wheeler. Wheeler also has had several traffic tickets in Ada County, including a citation for speeding in January.
