The San Francisco Police Department has issued an alert for a missing seven-day-old girl who investigators say is at high risk of neglect. The infant was last seen on Monday with her mother, 33-year-old Kenisha Davis, leaving the Target store at Geary Boulevard and Masonic Avenue, according to a statement released Tuesday. Police did not specify the circumstances that led them to classify the child as at risk but urged anyone who sees Davis or the baby, or who has information about their whereabouts, to call 911 immediately. No Amber Alert had been issued as of Tuesday afternoon, and authorities have not released a description of the infant beyond her age and gender. The department has circulated surveillance images of Davis taken outside the store and is coordinating with local hospitals and child-welfare agencies. The investigation remains active, and officials stressed that time is critical given the baby’s age and the potential for medical complications in newborns.
