A Smyrna woman has been arrested and charged with murder after she allegedly shot and killed her husband at their home.

The incident occurred at approximately 3:06 a.m. Wednesday after a 911 call was placed from a residence located in the unit block of Sugar Maple Lane in the Willowwood Development. Police said the initial call was an immediate disconnect from the caller and a dispatcher from the Kent County Emergency Operations Center re-connected making contact with Amanda G. King, 57, of Smyrna, who stated she shot her husband.

Delaware State Police troopers and officers from the Smyrna and Clayton police departments responded to the residence, where they immediately took Amanda King into custody without incident, police said. Detectives were able to recover a Glock .45 caliber semi-auto handgun located in the kitchen of the house, police said.

Police said King's husband, James E. King, 68, was located just inside the residence near a staircase with a single gunshot wound to the upper torso. He was transported to Kent General Hospital, where police said he was later pronounced dead. An autopsy was conducted by the Office of the Chief Medical Examiner, who ruled the cause and manner of death to be homicide by a single gunshot.

King was transported to Troop 3, where she was arrested for first-degree murder and possession of a firearm during the commission of a felony. Police said King was later transported to Kent General Hospital for unrelated health issues and turned over to the Delaware Department of Corrections to be held without bail.

Police said a motive in this case has not been established and the investigation is ongoing.
