of many of the Prostitute Killer's victims were found at various stages of decomposition, any fingerprints or biological traces of the suspect could not be located quickly enough, and therefore, the killer's identity is still unknown. A local resident, who was about 30 at the time of the first killings and knew the neighborhood well, was declared a suspect, but never charged. In two instances, police found witnesses who described the criminal as a middle-aged white male. In 2005, based upon results from DNA profiling, 52-year-old Billy Edwin Reid was arrested and charged with the 1989 murders of Lannell Williams and Lisa Kelly. Reid was convicted and sentenced to life imprisonment. He is suspected of committing several more murders, including some committed by the Denver Prostitute Killer, but no evidence incriminating him has been located. Another possible suspect is Vincent Groves, a man linked to several murders in Denver almost two decades after his death. According to the Denver Police Department, Groves could have been responsible for more than 20 murders of young girls and women in the area, around the same time frame when the Prostitute Killer was active.
