Just days after the news that a teenager stabbed his little brother to death, police have revealed why.

The boys were fighting over the sound of the speakers connected to the computer, WSVN 7 is reporting. William Gorzynski, 15, eventually stabbed his little brother, 14-year-old Matthew, in the chest, killing him in the family’s Coral Springs home on Monday.

“The two brothers were having a dispute over the sound of the speakers that were hooked up to the computer. The dispute actually escalated to where it became physical. William armed himself with a kitchen knife from the kitchen and actually stabbed Matthew one time in the chest,” an officer told WSVN.

How an argument over volume escalated to such a tragedy still has investigators and the family puzzled. Gorzynski faces second-degree murder charges and is currently being held in the Broward juvenile detention center.

Autopsy reports Wednesday confirmed it was a single stab wound that took Matthew’s life.

A memorial of cards, notes and flowers litter the sidewalk near the Gorzynski house and many neighbors described the boys as loving and nice kids. William Gorzynski wanted to be a culinary chef, his attorney told a judge Tuesday.

But those plans will likely be on hold while investigators sort out this sad situation.
