Robert Casson, 50, was found deceased in his Hazel Dell home near the 300 block of NW 88th Street. Casson, a TriMet bus driver in Portland, died from multiple stab wounds. 

Several items were stolen from his residence, including his Cadillac, which was later recovered in northwest Portland. 

Casson was known to socialize with men at his home, and investigators believe this may be relevant to understanding the circumstances surrounding his homicide. The case remains unsolved.
