On May 6, 1986, Portland police found 79-year-old retired businessman Joseph Murawski after a neighbor reported suspicious activity at an apartment at 4066 NE Grand Ave. Murawski told officers he had been lured the previous day by two people who offered to return stolen property for $50. He paid a down payment but refused to hand over the remainder without seeing his belongings, so the pair persuaded him to go to the Grand Avenue apartment to retrieve them.

Once inside, Murawski was struck from behind, knocked to the floor and kicked repeatedly while the assailants robbed him. He survived the initial attack and provided descriptions: a light-complected African-American man in his late 20s or early 30s, with a mustache and weighing about 180 to 190 pounds; and an African-American woman in her late 20s or early 30s, medium build, 140 to 150 pounds, with short natural hair. Neighbors recalled Murawski was generous with money, which investigators said may have made him a target.

Murawski was hospitalized after the beating, later suffered a brain hemorrhage and fell into unconsciousness. He died about eight weeks after the assault; the medical examiner ruled the death a direct result of the beating. The case remains unsolved and no arrests have been announced. Know anything that could help identify the two people who brought him to that apartment?
