Two of the highest-ranking civilian employees of the Department of Emergency Services and Public Protection, including the chief financial officer, left their positions after an internal affairs investigation, and another state employee has been on paid leave since December in relation to the case. State officials are keeping the details of the investigation and the allegations against the workers secret, even though the state police investigation concluded months ago. Aimee Plourde, who was hired as the agency’s CFO in the summer of 2022, and Scott Devico, who played a role in Plourde’s hiring as an executive assistant to then-DESPP Commissioner James Rovella, both left state employment in June after the investigation was completed, according to the state Comptroller’s office. Devico’s “status is now terminated from DESPP, effective 06/28/2024,” wrote spokesperson Madi Csejka in an August email to The Connecticut Mirror. In a separate email, Csejka wrote: “Aimee Plourde has been terminated by DESPP, effective 06/05/2024.” Plourde was placed on paid administrative leave in December 2023 by DESPP Commissioner Ronnell A. Higgins, who had been named to the post just a few weeks earlier. Plourde was a 17-year state employee, earning about $140,000, when she was placed on leave. She had been a tax unit manager at the Department of Revenue Services, earning about $116,000, when she got the DESPP job in May 2022. An employee of the Department of Administrative Services, Marybeth Bonsignore, was also placed on paid administrative leave at that time and was investigated by state police detectives. Bonsignore, who has been a state employee for 37 years, is still on paid administrative leave while the Office of Labor Relations handles her employment case. Her salary is $146,000, according to DAS officials. Higgins sent a letter to Devico, who was a political appointee, on June 14. It states: “Effective June 14, close of business, your appointment in the position of Executive Assistant 2 at the Department of Emergency Services and Public Protection (DESPP), serving as defined in section 4-5 of the Connecticut General Statutes under Commissioner Ronnell Higgins, will end.” Devico declined to comment and Plourde did not respond to requests for comment. Bonsignore has hired attorney Bruce Newman of Brown, Paindiris & Scott to represent her. Newman did not respond to a request for comment Monday. The internal affairs report has been shared with DAS officials. Agency spokesman Leigh Appleby said this week that Bonsignore’s case is still going through the labor relations process. The CT Mirror filed a request in June under the state’s Freedom of Information Act for the state police internal affairs investigation after it was completed, but the agency has refused to release the report. “We are ready and eager to release the internal investigation report as soon as the disciplinary process has been completed,” DESPP Director of Communications Richard Green said last week. Appleby cited a portion of the FOI Act exempting documents from disclosure that are the subject of ongoing litigation. Devico and Plourde’s employment ended after Higgins received the internal affairs investigation results in June. Devico had been a state employee for 28 years and was earning about $153,000. “We have two members of the leadership team (one from Human Resources and one from Fiscal) who are on a leave of absence,” Higgins said in a statement last December. Even though she is a DAS employee, Bonsignore was assigned to work with the human resources department at the state police when Plourde was hired. Because Bonsignore is not a state police employee, Higgins has no authority over her employment. Instead, Bonsignore’s case has been handled through the state’s Office of Labor Relations. “The investigation (which was jointly conducted by DESPP IA and OLR, not DAS) has been completed,” Appleby said. “However, the follow-up decisions and potential actions remain pending.” Appleby said that Bonsignore will remain on paid administrative leave pending the outcome of the investigation and finalization of next steps. Correction An earlier version of this story incorrectly reported that Scott Devico had been placed on administrative leave. He was not placed on leave before his employment ended. The story has also been updated to clarify the nature of his separation from state employment.
