KEENESBURG, Colo. -

A suspected kidnapper and a boy are dead after a standoff with deputies in Weld County.

Sheriff John B. Cooke says the standoff started Monday night after SWAT officers went to a house to serve a warrant for the suspect. He barricaded himself inside the home with a boy. The boy told negotiators that he was there voluntarily and refused to leave.

At around 1:30 a.m. Tuesday, deputies stopped hearing from the two. A camera was deployed inside and found two bodies on the floor.

Authorities haven't released the identities of the suspect or the boy yet.
