HARTFORD, Conn. (AP) — Anguished mothers with mentally ill children have sought out Liza Long for help ever since she wrote an essay, “I am Adam Lanza’s Mother,” comparing experiences with her son to the emotionally troubled 20-year-old who carried out the Sandy Hook Elementary School shooting. The massacre sounded alarms nationally about gaps in mental health care and led to calls for better screening and services, especially for young people showing a propensity for violence, but some key reforms enacted in the wake of the Sandy Hook shooting depend on funding that has yet to be delivered by Congress. And Long still hears almost daily from families overwhelmed by their children’s behaviors and struggling to get treatment.
