A sheriff deputy said a Mississippi man decapitated his mother with a butter knife, his teeth and bare hands.

Terrelle Johnson, 29, of Wiggins, Mississippi confessed to killing his mother Sherry Johnson, 51, a high school guidance counselor, earlier this month. Her body was found by police outside her home on June 6.

Terrelle Johnson was charged with first-degree murder.

Capt. Ray Boggs of the Stone County Sheriff’s Office testified at a preliminary hearing this week that he went to Johnson’s home for a “welfare check” after the woman’s siblings contacted authorities when they had not heard from her for a few days.

Terrelle Johnson reportedly told his mother’s relatives that she was away on a cruise but they were not convinced.

Boggs said when he went to the home he saw Terrelle Johnson outside who told him his mother was fine. The deputy insisted he look around inside the home and Terrelle led him and two other officers inside the home where they saw blood.

“When I entered the bedroom, I immediately noticed blood everywhere,” he said, adding the walls and bed also had blood on them.

In the backyard, the found Sherry Johnson’s body. Her head was found about 15 feet from her body.

Following the crime scene investigation, the deputies interviewed Terelle Johnson who allegedly confessed to killing his mother. He said they got into a fight over credit cards and he choked her until she stopped breathing.

“He told me that he beat her up real bad,” Boggs said. “He said it got out of hand.”

After he choked her, Terelle Johnson decapitated her using a butter knife along with his hands and teeth, Boggs said. He then moved the body outside so the home would not smell.

A relative said Terrelle Johnson served in the U.S. Army when he was young and enrolled in community college. Boggs said Terrelle Johnson was expelled from the Department of Veterans Affairs because of a previous arrest.

His father, Rev. Rob Harris, was present during the hearing but did not comment.

Jim Davis, Terrelle Johnson’s lawyer, said they were considering an insanity defense.

“[Johnson] does have a substantial history, and y’all heard the facts of this particular case,” Davis said. “That’s not a normal homicide … [but] we’ve got to wait until we get the records and probably have him properly evaluated. Then, we’ll kind of know where we’re headed.”
