LAS CRUCES, N.M. -- A California woman shot and killed herself while driving on Interstate 10 in New Mexico while her 9-year-old daughter was inside the vehicle.

The girl wasn't injured.

State police Lt. Roman Jimenez says the woman shot herself in the chest Thursday about 25 miles west of Las Cruces - after the girl refused the woman's request to kill her.

The girl told investigators her mother began to breathe heavily - possibly from an asthma or emphysema attack - and handed over a 9-mm handgun.

The girl refused.

The woman then fired a shot into her own chest and the car rolled to a stop on the road's left shoulder.

The woman and her daughter were traveling to Oklahoma City to see the girl's father.
