Keisha Yvette Nixon (DeSoto Police Department)

A woman faces aggravated assault charges after DeSoto police say she shot her husband multiple times and left him in critical condition.

Keisha Yvette Nixon, 47, was arrested Friday and is in the Dallas County Jail awaiting arraignment, DeSoto police spokesman Pete Schulte said.

The shooting occurred around 1:45 p.m. Wednesday in the 900 block of Place Louie.

Nixon initially told officers she shot her husband in self-defense after an argument, but detectives determined her story did not match up with evidence.

Nixon faces a charge of aggravated assault with a deadly weapon causing serious bodily injury to a family member, a first-degree felony.

Her husband was taken to an area hospital with several serious injuries, Schulte said.

Additional charges are possible as the investigation continues, Schulte said.
