Caddo sheriff's deputies have arrested a Vivian teenager for stabbing his parents.

Sheriff Steve Prator says 17-year-old Shane Alexander woke his father and step-mother at around 3AM and stabbed them both with a knife at their home in the 10000 block of Upper State Line Road.

Detectives say 61-year-old LaDonna Alexander was stabbed once in the chest. She drove herself to North Caddo Memorial Hospital, where she was treated and released. Sixty-four-year-old Jerry Alexander was stabbed in the back and arm. He locked himself in the bedroom and called 911. He was later transported to University Health with non-life-threatening wounds.

Shane was taken into custody, then booked into Caddo Correctional Center on two counts of attempted first-degree murder.
