KANSAS CITY, Mo. (AP) — A Kansas City man has been charged with stabbing his ex-girlfriend in the neck while she was working at a Walmart store.

Twenty-two-year-old Brian Lenoble Jr. is charged with first-degree domestic assault and armed criminal action. No attorney is listed for him in online court records.

Court records say an off-duty officer arrested him Dec. 31 in the parking lot. Lenoble told the officer, “I tried to kill her and slit her throat and I would do it again.”

The officer went into the store, where he found the blade still embedded in the woman’s neck. She was taken to a hospital with serious injuries.

A family member told police that Lenoble had been diagnosed with bipolar disorder and post-traumatic stress disorder.
