Police have arrested a suspect in a deadly shooting that left a pregnant woman dead and six others injured inside a Spirit Halloween store in Northern California last week.

The Fairfield Police Department announced the arrest Monday, just days after gunfire erupted inside the seasonal Halloween retailer at Solano Town Center around 8:30 p.m. Friday, according to CBS.

Authorities have not yet released the suspect’s identity or details about the charges they may face.

The woman killed in the terrifying attack was identified as 31-year-old Constance Hages, whose family told investigators she was pregnant at the time of her death.

Six other people were wounded in the shooting, including a 19-year-old man who remained in critical condition as of Sunday.

Three additional victims were still hospitalized in stable condition, according to authorities.
