A registered violent offender is charged with two counts of deliberate homicide for killing a man and his mother during a confrontation over the theft of 1,700 ounces of silver.

Powell County Attorney Lewis Smith filed charges against 53-year-old David Wayne Nelson in District Court on Tuesday.

Nelson is charged with killing Gregory Giannonatti and Beverly Giannonatti on Oct. 24 or 25 in the bathroom of Beverly Giannonatti's deceased ex-husband's house.

Prosecutors say Nelson told investigators Greg Giannonatti confronted him and he hit him in the face and then with a hammer. Nelson said he pushed Beverly Giannonatti down before strangling her with electrical wire.

Nelson is also charged with stealing the silver and obstructing justice by hiding the bodies and other evidence.

Sheriff Scott Howard said Nelson did not appear in court Tuesday.
