Case 74

Eric Coy

*** Warning: This case involves a child victim ***

On the morning of January 24 1987, nine-year-old Eric Coy hopped on his bike to make the one-mile journey to his cousin Eddrick’s house in the Northern Californian town of Martinez. The two boys were best friends and it was a trip Eric had made countless times before. Eager to get there as quick as he could, Eric took a shortcut.  

Just 15 minutes later, a group of children found Eric’s lifeless body near a footbridge at Alhambra Creek. He had been stabbed multiple times, but by who? And how did they get away undetected in such a short amount of time?
