JACKSONVILLE, Fla. (AP) - The son of a woman whose decapitated body was found in her home in north Florida has been declared mentally unfit to stand trial.

Forty-three-year-old Jennifer Renee-Henry Ling was found in her home in April in what authorities call a gruesome crime scene with bloody hand prints covering the house. Her decapitated head was found a few blocks away.

Twenty-two-year-old Jumar Henry has been charged with first-degree murder. The state has said it will seek the death penalty.

In September, Circuit Court Judge David Gooding ordered him sent to a mental health treatment facility to evaluate his competency.

His grandfather and former cop, Laurence Ling Sr., has nagging questions about the charges. He says more than one person could have committed the crime.
