COSTA MESA — Robyn Cox died violently on a bright winter's day in January 1977.
Murdered the afternoon of Jan. 12, Cox's 5-feet-2, 107-pound body wasn't discovered until that night, when her roommate found it inside their Costa Mesa apartment upon returning home from work.
Cox, 20, appeared to have been strangled or forced to drown in the bathtub, according to a Los Angeles Times article.
The victim was single, had no children and wanted to be a court reporter, but hadn't started studying for that profession, said police Det. Dave Casarez.
What police do know is this: Whoever killed the Coco's Restaurant waitress left investigators little to work with when police reached the crime scene in the 200 block of Avocado Avenue.
