CENTENNIAL, Colo. (KCNC) - Devastating and heartbreaking, words that carry so much weight. But still, it isn’t enough to accurately describe what a Colorado family is going through.

Their youngest child is dead, and another child has been charged with murder.

The Arapahoe County Sheriff’s Office said a 5-year-old boy was killed at his home this week.

Investigators believe the boy’s 11-year-old brother is responsible.

The news is hard to absorb for neighbors who shared that their kids played together.

“It’s something that you know, as a parent, is probably your worst nightmare,” neighbor Kirby O’Loughlin said.

Wednesday afternoon, deputies performed a grid search in an area behind the home.

The 11-year-old is now in custody at the Foote Youth Services Center in Centennial. He faces a first-degree murder charge.

“My heart goes out to the family,” another neighbor, Emily Silengo, said. “To hear that makes me pretty emotional.”
