Around 12:30 a.m. on Jan. 8, 2012, unknown suspects fired shots into a home near 75th Avenue and Indian School Road where an underage drinking party was taking place.
One of the rounds went through the house and into the backyard, striking Fabian Cano in the head.
Cano, 19, died from his injuries a few days later.
No suspects were identified.
Silent Witness is offering a reward of up to $1,000 for information that could solve the case.
