TOPEKA, Kan. (AP) — A  Kansas man is charged with first-degree murder in the death of his mother.

Shawnee County District Attorney Mike Kagay announced Thursday that David Wood Jr., 43, Topeka, is charged in the death of 69-year-old Kyong “Carol” Wood. He is also charged with felony interference with law enforcement.

Investigators say the victim was found dead Sunday inside her home. Kagay says she died from blunt force trauma.
