MISSOULA, Mont. (AP) — A former patient and former employees of a now-closed children’s psychiatric hospital in Montana have filed lawsuits against Tennessee-based Acadia Healthcare, which owned Acadia Montana in Butte. Acadia Montana closed its 108-bed hospital in July after Oregon officials questioned its use of injected medications to control the behavior of a 9-year-old girl. The former patient alleges negligence and assault while he was a patient at Acadia seven years ago. The former employees are seeking back pay alleging Acadia Healthcare violated a federal law that requires employers to give 60 days notice to employees before a layoff of more than 100 people. Acadia did not respond to the former patient’s lawsuit and says by the time it closed it had just 30 employees.
