He was identified “fairly quickly” after the shooting with the help of a school resource, officer but police didn’t want to compromise his whereabouts, Fairfield Police Chief Dan Marshall said.

Constance Hages, a 31-year-old woman who was pregnant, was killed in the shooting at Solano Town Center.

The other victims ranged in age from 16 to 43 years old. They included a 16-year-old boy, a 19-year-old man, a 32-year-old man, and a 23-year-old man who all remained hospitalized. The 19-year-old man remains in critical condition while the 16-year-old boy, 32-year-old man and 23-year-old man are in stable condition.

Two other victims, a 19-year-old man and a 43-year-old man, were released from the hospital after being treated for gunshot wounds.

Marshall said the suspect had served a few months in juvenile hall in connection with a shooting at a high school parking lot in 2025.

He called for legislative changes to hold youth offenders more responsible for violent crime.

The identity of the suspect, who is being charged with murder and attempted murder, was not released because of his age.
