A 15-year-old Tacoma boy accused of stabbing another teenager to death with his brother pleaded not guilty to first-degree murder and robbery this morning.

Pierce County prosecutors charged Cristobal Arroyo as an adult. His brother, Luis Arroyo, has pleaded not guilty and remains jailed in lieu of $2 million bail.

The brothers are accused of killing 15-year-old Hector Hernandez-Valdez on June 1, 2012. Prosecutors contend the brothers attacked Hernandez-Valdez at their home in the 800 block of East 52nd Street with a knife and a shank, stabbing him dozens of times before dumping the dying boy in the bathtub and cutting his throat.

The Arroyos then hid the body in a recycling bin, where their mother found it.

Prosecutors believe the brothers attacked Hernandez-Valdez so they could rob him of cash and marijuana but the boys told police they attacked him after he punched Luis Arroyo for no reason, according to court records.
