He shot his parents for not letting him play Halo 3

The trial of the 17-year-old who killed his mother and shot his father because they wouldn't allow him to play Halo 3 opened this Monday.

In September 2007, Daniel, then 16, had sneaked out of his bedroom window to purchase the game at a store against his father's orders. When he returned home, his parents caught him with the game and took it from him. His father, Mark, a minister at New Life Assembly of God in Wellington, put the game in a lockbox in a closet where he also kept a 9mm handgun, according to prosecutors.

About a month later, on Oct. 20, 2007, Daniel used his father's key to open the lockbox and remove the gun and the game. The boy shot his parents, killing his mother and gravely wounding his father. As his father lay wounded, Daniel tried to place the gun in his father's hand.

Petric, 45, said he "expected a pleasant surprise" and closed his eyes. Then his head went numb. As the blood poured from a bullet wound in his head, he realized his wife, Susan Petric, 43, was lying dead on a nearby loveseat, shot in the head, arms and chest. - Read article
