 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 the Elm City and two other states in the last week. Company CEO Peter Shore and his chief administrative officer both died by suicide in the last week as the company imploded. Company chief financial officer says it simply ran out of money and that 750 employees were not paid last week.
