Napa State Hospital patient attacks therapist

A patient has beaten a therapist unconscious at Napa State Hospital, an attack that comes less that two months after a psychiatric technician was strangled at the California facility.

The latest attack Saturday occurred in a secluded corner of the hospital grounds. The 60-year-old rehabilitation therapist is hospitalized with four skull fractures.

The Los Angeles Times says 24-year-old Sean Bouchie has been booked into Napa County Jail for investigation of felony battery.

Security measures have been stepped up at Napa State Hospital since psychiatric technician Donna Gross was strangled in October. A patient has been charged with murder.
