 The company that ran the retreat behavioral health rehab centers in New Haven owes the city $230,000 in back taxes. Retreat abruptly shut down its inpatient and outpatient rehab centers in New Haven and two other states in the last week. Company CEO Peter Shore and its chief administrative officer both killed themselves in the last week as the company imploded. Company chief financial officer says they simply ran out of money and that 750 employees were not paid last week.
