John Dwight Canaday (1945 – December 26, 2012) was an American serial killer who raped and killed three young women in Seattle from 1968 to 1969.

[1] In the early hours of December 17, 1968, 16-year-old Sandra Bowman, a pregnant newlywed, informed her husband Thomas that she had fallen ill, and was going to be bedridden for the rest of the day.

Hours later, when Thomas returned home from his job at a canning company, he discovered Sandra stabbed to death, with her hands bound behind her back.

[3] By March 1969, Seattle police launched an investigation into Canaday, a divorced Vietnam War veteran, who had been accused of raping two women.

In the end, a jury deliberated for only two hours to find Canaday guilty on all counts, on the basis of which days later he was sentenced to hang.

The Washington State Crime Lab agreed to examine the evidence from Bowman's murder and subsequent autopsy in hopes of finding new clues.
