A former Portland police sergeant was sentenced on Friday to serve 60 days in jail and pay $159,000 in restitution for stealing from a family member while he had power of attorney over her finances.

Bruce Chase, 63, of Naples, pleaded guilty in the Cumberland County Courthouse in Portland to a felony charge of theft and a misdemeanor charge of misuse of entrusted property.

Justice Roland Cole also sentenced Chase, who retired in good standing from the Portland Police Department in 2000, to serve two years of probation after completion of his jail term.

Chase had convinced Penelope Cobb, his friend and family member, to give him power of attorney in 2008 while he attended the funeral of her husband, Donald Cobb. Starting within a month afterward and continuing for four years, Chase diverted $159,000 of Cobb’s money for his personal use, according to the Cumberland County District Attorney’s Office.

Cobb discovered in early 2014 that she had only $2,000 left. She reported the theft and sought public assistance for oil and food as her home almost went into foreclosure, the DA’s office said in a statement.

“Bruce Chase had a duty as a Power of Attorney to protect Penny Cobb’s financial interests. He violated that duty in the most reprehensible of ways by stealing and squandering her money. As a friend of 40 years and a former law enforcement officer, he knew better,” Assistant District Attorney Tracy Gorham said in a written statement after Chase was sentenced.

District Attorney Stephanie Anderson said that her office agreed to the “low jail sentence” in exchange for what she called an unprecedented amount of restitution that Chase’s family paid to Cobb.

Chase began working for the Portland Police Department as a public safety officer from 1980 to 1982. He became a police officer in 1982, reaching the rank of sergeant. He also worked during his career as an agent for the Maine Drug Enforcement Agency and as an internal affairs investigator for the Cumberland County Sheriff’s Department.

Portland police Detective Kelly Gorham investigated the case against Chase in conjunction with the prosecutor, Tracy Gorham, who is not related to her, and Cumberland County’s Financial Director Alex Kimball. Together, they spent more than 1,000 hours piecing together the details of the complex case, the DA’s office said.
