ISLAMORADA (AP) — A teenager in the Florida Keys killed his younger brother, stabbed his father and then ran in front of a truck after a daylong search for him, authorities said Friday.
The Monroe County Sheriff's Office said in a news release that the 17-year-old old boy was taken to a hospital in Miami with severe injuries Thursday evening. Authorities released his name, but The Associated Press does not generally identify juveniles who have been charged with a crime.
A neighbor called deputies Thursday morning after the teen's 43-year-old father approached him, saying the boy had fatally stabbed his 14-year-old brother and then stabbed him multiple times, including in the neck.
Investigators weren't sure what motivated the teen to attack his brother and father, the news release said.
The brother was pronounced dead at the scene, and the father was airlifted to a trauma center in Miami.
Online court records show that first-degree murder and aggravated battery charges initially were filed in circuit court against the teen. But a subsequent clerk's affidavit said the filing was in error and the case should have been filed in juvenile court, which has strict confidentiality restrictions.
