Here are the facts of the case:

  • Around 11 am on January 24, 1987, Eric left his house on Warren Street for a friend’s house (other news sources say he was headed to his aunt’s house). Eric’s destination was approximately a mile away from his home.
  • Eric rode his bike and took a seemingly safe route known to kids in the area. He took a shortcut through Martinez Junior High School towards Alhambra Creek.
  • Within 15 minutes of leaving his house, Eric was found by a group of kids near a footbridge crossing Alhambra Creek. This location is directly west of the junior high school.

  • Eric was stabbed 11 times by a sharp object or a knife that was approximately 6-7 inches long. He sustained wounds to his upper torso and one wound to his neck.
  • Investigators learned that in the days leading up to the attack, there may have been a disagreement between the Coy family and a neighbor. However, there is no further information to prove or discredit this claim.
