SANFORD – The state Department of Human Services has begun an investigation into the death last month of an elderly woman at an adult care center.

The investigation at Parkview Manor South uncovered violations of rules governing patient medication, but officials would not say what caused the Feb. 22 death.

DHS also would not release the woman’s name, citing patient confidentiality requirements. But Monique Morin of Sanford confirmed Thursday that the woman was her aunt, Cecile Cloutier, 92, also of Sanford.

Catherine Cobb, community resource development director for DHS Bureau of Elder and Adult Services, said the investigation prompted the state to require retraining for employees of the six-bed residential care home.

“We thought some of the staff should be reassigned to other than medication duties,” she said.

There have been no other sanctions against the center, Cobb said, but the investigation is continuing.

Parkview and the Family Living centers in Biddeford and Saco have been operated for the past month by a court-appointed receiver, First Atlantic Corp. of Portland.

The receivership began after employees complained about supply and food shortages and what they believed was the likelihood that the owner, Adult Care Centers of America, would be unable to meet its payroll.

Ken Bowden, First Atlantic president, said there may be changes in clinical practices pending resolution of the incident at Parkview Manor South. No Parkview employees have been disciplined or fired as a result of the investigation, he said.

Additional training, which included checks of medications of other residents, began Monday for the center’s staff, Bowden said.

On Feb. 8, a Kennebec County judge appointed First Atlantic as receiver for Adult Care Centers of America’s six residential care facilities in Sanford, Biddeford and Saco.

Besides seizing bank accounts, the court indicated it would freeze the assets of the centers for failure to pay unemployment contributions, interest and penalties totaling more than $41,000.

The six facilities, which have about 100 residents and nearly as many employees, are owned by Donald Baldyga, of West Orange, N.J.

Baldyga said some revenues from the centers were used to pay for corporate office expenses and to help bolster a 20-bed Village Manor facility he owns in New Jersey.
