MARIO RIVERA

On December 10, 1981, an employee of the Oregon Humane Society was near a pond on the 1000 block of NE Columbia Boulevard at approximately 12:40 pm, when he observed what looked to be a red parka in the pond. Upon further inspection, he discovered that it was a deceased individual. Police responded to find the victim, Mario Rivera, a 42-year-old Hispanic man.  An autopsy revealed that he had died as the result of being beaten about the head with a blunt object.

Mario Rivera was described, by most individuals interviewed, as being rowdy and was frequently drunk. He was also reported to be verbally abusive and disrespectful.

Witnesses reported seeing a red object in the pond, similar to his parka, as early as Monday, December 7.
