LIBERTY, Mo. -- DNA from chewed chicken bones led prosecutors to file charges against a Kansas man in connection with two 2006 burglaries in Gladstone, Mo.

The Clay County prosecutor charged John Wyatt Weaver, 43, with burglary and stealing a firearm.

Prosecutors accused him of entering two homes in the 100 block of Point Drive in Gladstone on Nov. 23, 2006, according to a news release.

At one home, the residents found nothing missing but some leftovers from the refrigerator.

While officers were at the home, police found a door kicked in at a neighbor's house.

Police contacted that neighbor, who reported several firearms were missing.

As they collected evidence at the crime scene, police found chewed chicken strewn throughout the home, and they determined they were part of the missing leftovers from the neighbor's home.

The chicken bones were processed for DNA evidence, and investigators -- using a national database -- matched the DNA to Weaver, the news release states.

Weaver had previously been convicted of burglary and automobile theft, which was why his DNA was in the national database.

He was already serving time in a state correctional facility in Hutchinson, Kan.
