JACKSONVILLE, Fla. -

The son of a woman whose decapitated body was found in her Jacksonville home in April has been declared mentally unfit to stand trial.

In April, the body of 43-year-old Jennifer Renee-Henry Ling was found in her home in what authorities called a gruesome crime scene, with bloody hand prints covering the house. Her decapitated head was later found in a plastic bag few blocks away.

Jumar Henry, 22, was charged with first-degree murder after his father noticed scratches on his face and blood under his fingernails and called police.

Detectives believe the homicide occurred during an altercation and the murder weapon was a steak knife that Henry found in the house.

In September, Circuit Court Judge David Gooding ordered him sent to a mental health treatment facility to evaluate his competency. A review of the case is scheduled for February.

The state has said it will seek the death penalty.

Henry's grandfather, former police Officer Laurence Ling Sr., has nagging questions about the charges. He said more than one person could have committed the crime.
