Woman accused of trying to kill her autistic daughter

A woman who was accused of trying to kill her autistic daughter has pleaded guilty to first-degree child abuse.

A prosecutor says Kelli Stapleton entered the plea Tuesday.

She'd been scheduled to go on trial today on a charge of attempted murder.

Stapleton is accused of trying to kill herself and her teenage daughter last year by carbon monoxide poisoning by igniting charcoal grills inside a van in northern Michigan.

Her daughter, who was 14 at the time, has severe autism and sometimes has violent outbursts.
