Florida police say an argument over loud music led a 15-year-old boy to fatally stab his brother.
The teen is being held in juvenile custody on suspicion of second-degree murder in his 14-year-old brother's death.
Coral Springs Police say the teen being held asked his brother to turn down the music playing on a computer. When he refused, police say the 15-year-old got a knife from the kitchen and stabbed his brother in the chest.
An attorney for the boy tells the South Florida Sun-Sentinel his client doesn't even believe it happened. The lawyer says the boys fought, "but they don't fight in an unusual way."
The teen called 911 soon after and told the dispatcher he had just stabbed his brother. Police say it's "actually a confession on tape."
