The cold case disappearance of Katherine Joy Allen - Denver, Colorado - July 2, 1996

When Katherine Allen, a 42-year-old mother of three, failed to show up for her daughter's graduation, her family became deeply concerned. Not only because she was not present for an important day of her daughter, but also because she had indicated that she was in danger after a drug robbery. According to Katherine, the danger was so great that if she didn't get help, she might not make it to the next day. This fear seemed to have come true when she wasn't there that day to see her daughter graduate.

Katherine had battled her addiction to crack cocaine for much of her life. Because of her drug problems, all three of her children were taken from her, and her youngest son was born addicted to hard drugs. Although she had no custody of her two daughters and son, she was in contact with them. Despite everything, the three loved their mother very much. They were therefore shocked when Katherine seemed to have disappeared from the face of the earth.

According to police, the 42-year-old was living at the Ahwahnee Motel in the 8500 block of East Colfax Avenue at the time of her disappearance. There, Katherine would put a lot of effort into stabilizing her life. She had been addicted to crack cocaine since the 1980s, and also had a long-standing alcohol addiction. The addictions significantly affected her life, and that of everyone around her.

The police could find no trace of Allen, and the case eventually went cold. In an emotional video call, her three now grown children called for people to come forward with their information. The three were still noticeably in pain and sadness about their mother's missing. The children suspect that Katherine must have been murdered, and that there are people who know what happened and where she is now.
