The state Department of Public Health has confirmed that there is an open investigation into Carlson Place, a retirement and assisted living facility in Norwalk.

A spokesperson could not get into specifics about what they are investigating. They said their job is to regulate for health care quality and safety and make sure the patients’ needs are being met.

Mark DiPietro, who has been living there since October 2019, says 27 people live at the residential care facility. He says many of the elderly patients are not fed properly and there are bedbugs in nearly every room.

DiPietro says the investigation is necessary and some residents were nervous to come forward.

"Some of these people haven't been out of the house in three to four months. They're scared to talk, they're scared to say anything," he says.

The Department of Aging and Disability is also involved in the investigation and is working to make sure the rights of residents are protected.

Employees at the facility referred all of News 12’s questions to the state Health Department, which said inspectors would be on site through the weekend.
