Denver is probably the home of a serial killer who preyed on homeless men during the Fall of 1999. The first killings were discovered on September 7 when Donald Dyer and George Worth were found dead under a loading dock. The very next day Melvin Washington was discovered bludeoned and died later as a result of his injuries. Next, Milo Harris was recovered floating in the South Platte River on September 26 and Kenneth Rapp's corpse was located on October 22, though he and Harris had obviously been killed at a much earlier date. All five bodies were found in the general area of Coors Field and the short proximity in time between their deaths leaves little doubt that a serial killer stalks Denver's homeless.

The Denver men's killer may have moved on. Boulder has at least two similar unsolved slayings of homeless men since Rapp's body was found, plus a 1997 case that could be connected. Denver authorities also fear that two beheaded males could be part of the same string of murders.

10/30/2004-Denver police have reported that they are investigating the deaths of at least 5 homeless men killed so far this year, though they claim none are likely related to the murders of in 1999. Also in the article it was revealed that the killing of Melvin Washington was solved. Three other homeless men have been convicted in his stomping death after they felt Washington infringed on their turf while panhandling. One of the men denies any connection with the other slayings in the series and police feel that the killer, or killers, is still on the loose.
