JACKSONVILLE, Fla.  - The son of a woman whose decapitated body was found in her home in north Florida has been arrested in connection to the killing. Authorities say 43-year-old Jennifer Renee-Henry Ling was found in her home on Sunday and her decapitated head in a bag a few blocks away.

Authorities say 21-year-old Jumar D. Henry tried to escape during his police interview on Sunday. He remains in jail without bond and faces charges including murder and battery on a law enforcement officer.

Authorities say witnesses told them he walked to the back of the property where her head was found, carrying a bag and then returned without it. They say his father saw him with injuries to his head. It wasn't immediately known if he had an attorney.
