Daniel Ruiz, a 37-year-old Hispanic man, was found dead in his Southeast Portland apartment in the 3700 block of SE 32nd Avenue in the early morning of March 6, 1987. His girlfriend discovered his body at about 2:30 a.m., and an autopsy determined the cause of death was blunt force trauma. Friends last reported seeing Ruiz alive late on March 4, leaving an unexplained window of roughly two days before his body was found.

Reports note Ruiz was a regular heroin user, but investigators have not identified a motive. The Portland Police Bureau’s Cold Case Homicide Unit lists the killing as unsolved; no suspects or arrests have been publicly named. If anyone knew Daniel, his movements in late February and early March 1987, or has information about who may have been with him during that period, the investigation would benefit from hearing from you.
