Colorado 11-Year-Old Charged With Murder in Death of 5-Year-Old Brother

An 11-year-old boy is being held at the Marvin W. Foote Youth Services Center in Centennial after Arapahoe County Sheriff's Office investigators determined his 5-year-old brother's death was a homicide and arrested him on suspicion of first-degree murder.

Deputies responded to a rental property in the 5200 block of South Jericho Way at approximately 5:30 p.m. Tuesday, March 11, after the younger boy was found dead. The street, lined with single-family homes, wide driveways, and green yards, remained closed Wednesday afternoon as the investigation continued. The specific cause of death has not been released, and the Arapahoe County Sheriff's Office has stated little is known at this time about what led to the child's death.

The 5-year-old was a kindergartner at Timberline Elementary School. Principal Mary Bowens sent an email to parents Wednesday addressing the loss. "There is no right or wrong way to cope with loss, but there are some things that adults can do to help students work through this difficult time," Bowens wrote. She urged parents to talk with their children and encourage them to seek adult support if struggling, closing with a direct plea: "Please hug your children — nothing is more important than our kids."

Neither child has been publicly identified. The Arapahoe County Sheriff's Office confirmed the juvenile suspect will not be identified because of his age. The older brother was taken into custody following Tuesday's incident and formally arrested on Wednesday on suspicion of first-degree murder. He remains held at the Marvin W. Foote Youth Services Center in Centennial.

Long-time neighbor Meher Noorulamin told reporters she was extending compassion to the family rather than rushing to judgment. "I think it's so easy to say, how did the parents not know? How did this happen? But without judgment, neighbor to neighbor, we're here for you," Noorulamin said.

Critical details remain outstanding: the Arapahoe County District Attorney's Office has not issued a statement confirming formal charges or juvenile court filings, no coroner or medical examiner findings have been released, and no arrest paperwork or court dates have been made public. The investigation is ongoing.
