Jurors in suburban Detroit are returning to court for their first full day of deliberations in the trial of a 75-year-old woman who shot and killed her teenage grandson.

The jury must decide whether to convict Sandra Layne of first-degree murder or a lesser charge, or acquit her on the basis of self-defense. Deliberations resume Tuesday in Oakland County, north of Detroit.

Prosecutor Paul Walton says there was nothing defensive about Layne's treatment of 17-year-old Jonathan Hoffman, who was shot six times last spring at their home in West Bloomfield Township.

Walton says Layne didn't flee her home or call 911 to seek help for Hoffman after he was shot. Layne's attorney says she feared her grandson and felt overwhelmed by his drug use and choice of friends.
