A 17-year-old, Monte Smith, faces murder and related counts after a shooting at a Spirit Halloween store in Fairfield, California, that killed 31-year-old Constance Hages, who was pregnant and a mother of four, and wounded six other people. Fairfield police said he had already been convicted of firing at an occupied vehicle in a high school parking lot last September, served a few months in juvenile hall, and was then released.

Prosecutors are seeking to try him as an adult, which California law allows only if a judge first finds he is not amenable to rehabilitation in the juvenile system. Three of the counts are felony assault with a semi-automatic weapon.
