A 75-year-old man accused of shooting and killing his mother was arrested and charged with murder Sunday night after being released from the hospital.

According to police, Leslie Charles Nelson was detained Sunday after calling Corpus Christi police to report the shooting in the 6500 block of High Arch Court. When they arrived and checked the home, they found Nelson's 94-year-old mother dead from what appeared to be a gunshot wound.

Police said Nelson had taken some pills prior to their arrival. He was taken to the hospital for treatment and arrested upon release.

Nelson's mother was later identified by the Nueces County Medical Examiner's Office as 94-year-old Vivian Nelson. Her cause of death was a gunshot wound to the head.

Corpus Christi police said their investigation is ongoing.
