A judge said the jury can consider first-degree murder, second-degree murder, voluntary manslaughter or involuntary manslaughter in the trial of 75-year-old Sandra Layne. She is accused of shooting her grandson six times in May 2012 at her West Bloomfield Township home.

Layne confessed to shooting 17-year-old Jonathan Hoffman in self-defense after he demanded $2,000 and her car to leave the state. But prosecutors said it was premeditated murder.

Layne testified last week, saying she bought a gun to protect herself because her grandson brought strangers to the home late at night. Hoffman had a history of drug use.
