Body of 7-year-old Colorado boy found hidden in home; 16-year-old girl arrested

Jordan Vong, 7, was last seen around 4:30 p.m. Monday, but wasn't reported missing for several hours, according to KMGH-TV.

Investigators searched the family home and discovered the boy's remains late Tuesday, KMGH reported. Vong's body had been hidden inside the home and Denver police Division Chief Joe Montoya said officials believe the child was "intentionally concealed."

While authorities have said their missing person case has turned into a death investigation, they have not revealed how the boy was killed.

They have also not revealed the relationship of the teenager to the boy or his family.

Montoya said, according to KUSA, that the child's family exhibited "some natural, human reactions," when they learned of his death.
