Just after dawn on July 16, 1992, a patrol officer found Antonio Alvarez, 52, in a sleeping bag at Washington-Jefferson Park at West 2nd Avenue and Washington Street in Eugene. Alvarez had been attacked while he slept and suffered fatal blunt-force trauma to the head, struck multiple times with what appeared to be a heavy tool, possibly a tire iron or a hammer. The scene was secured and investigators conducted interviews and canvasses, but the case eventually became a cold case without a named suspect.

No arrest has been announced and detectives continue to seek information. Tips can be submitted to Crime Stoppers; qualifying information may be eligible for a reward of up to $2,500. Does anyone who was in or around Washington-Jefferson Park that morning remember seeing anything unusual or anyone who might be connected to this attack?
