An 11-year-old Colorado boy was arrested for the murder of his 5-year-old little brother on Wednesday.
The unidentified kid faces charges of first-degree murder, although officials revealed few details of the Tuesday night death that rattled the affluent suburb of Centennial, near Denver.
“This is an open and active investigation … Because both the victim and the suspect are minors, the information we release will be limited,” the Arapahoe County Sheriff’s Office said in a Wednesday statement.
Horrified residents of the quiet, family-friendly neighborhood witnessed a chilling scene Tuesday night as police wheeled the tot’s body into an ambulance.

“I pulled in, I was grabbing dinner, and then I saw two or three cop cars, which is definitely alarming, because we don’t usually see cop cars at all in here,” neighbor Kirby O’Loughlin told CBS Colorado.
The boys seemed to have a normal, peaceful home life; one neighbor said the victim and his two brothers were playing with neighborhood kids just days before the killing, according to CBS.
