As earlier reported on AntiPolygraph.org, a former Cumberland County, Maine sheriff’s deputy and polygraph operator, Regan J. Goan, was arrested on Friday, 11 September 2026 and charged with a series of misdemeanor crimes associated with his work as a polygraph operator.
Portland, Maine television station WGME has more details about the charges. On Tuesday, 15 September 2026, WGME staff reported:
PORTLAND, Maine (WGME) — New details have been released about a former detective with the Cumberland County Sheriff’s Office accused of falsifying records while working as a polygraph examiner.
Fifty-one-year-old Regan Goan is accused of not giving someone a polygraph exam five years ago when they were supposed to receive one.
The person was applying for a position at the Cumberland County Jail.
Court documents say the person was nervous, and Goan told them, “You know what, you’re good, buddy.”
Goan had his own polygraph business. Goan is also a former Bridgton police officer and Cumberland County sheriff’s deputy.
He was arrested Friday and charged with unsworn falsification, violating the Maine Polygraph Examiners Act and multiple counts of tampering with public records.
Later the same day, WGME’s CBS 13 I-Team investigative reporter Dan Lampariello reported additional details about the case:
PORTLAND (WGME) — A former Cumberland County Sheriff’s Deputy and police officer is accused of lying about conducting polygraph exams.
He also faced discipline in the past during his time with Cumberland County.
Regan Goan is facing multiple charges, accused of lying about polygraph exams he was supposed to conduct for the Cumberland County Sheriff’s Office through his private company.
Goan also received reprimands over the years while working as a deputy at that same agency.
Goan had worked as a Cumberland County Sheriff’s Deputy since the mid-1990s.
Later, he left to work as an officer in Bridgton and started his own polygraph examination company.
It’s through that company court records allege Goan lied about conducting polygraphs for nine law enforcement officers between 2019 and 2025.
He’s now facing charges of violating the state’s Polygraph Examiner Act and tampering with public records.
But the CBS13 I-Team has learned Goan was also disciplined multiple times as a deputy for other issues.
According to a copy of his personnel file, there are eight written warnings and reprimands.
They include one from 2021, when Goan let his polygraph examiner’s license expire for more than a year.
In 2019, he was reprimanded for failing to show up to a scene while on call. In that incident, he had to be woken up at his home.
That same year, he was also reprimanded for replacing the sim card in his county-issued phone and disabling it, even though the county was still paying for the plan.
The I-Team also requested Goan’s personnel file from his time with the Bridgton Police Department, but that is still pending.
The CBS13 I-Team reached out to Goan for comment Tuesday on the charges against him but never heard back.
In view of polygraphy’s complete lack of scientific underpinnings and its vulnerability to simple and effective countermeasures that anyone can learn, now would be an expedient time for the Cumberland County Sheriff’s Office to follow the example of the Omaha Police Department and stop using it.
