LYNN -- Have you ever gotten the feeling that your spouse is lying to you? Or that a salesperson was hiding the truth for the purpose of a sale? If so, Private Investigator Michael Coller can help you decode what is a lie and what is the truth with the help of his CD titled “The Seven Signs of Lying.”

Coller, who has more than 20 years experience in corporate security, has become an expert in knowing how to spot a liar. As a licensed Investigator by the Massachusetts State Police and a sworn Constable within Essex County, Coller has pinpointed the seven tell-tale signs of lying and recently poured his wealth of information into a CD to help the public do the same.

“I figured if I could do it to help a big company and provide credible defense for clients, then why not help people do the same?” he said.

Coller came up with the Honesty motto: hands, open posture, nervous, eyes, story, test and asking why to reveal certain signs of lying. Once those signs are mastered, Coller said the truth will come out.

“Look at their posture, are their arms and legs folded?” he asked. “If so, that means they’re not open for questioning at the moment. When you know someone, it’s easier to play the sympathy card by saying, maybe I’m wrong, or maybe I haven’t paid enough attention to you. Play on what they did to get the truth out.


Visualization is just one of the tools used in the CD to prepare those who are looking for the signs of lying in another person. By relaxing and envisioning questions that they want to ask and different angles that they may have to take, Coller said people can remain sharp and alert, while also being able to pick up on often unnoticed details and behaviors that liars exhibit.

“Visualization is huge,” he said. “I spend about 10 minutes by myself preparing before I question someone, because interviewing is so unpredictable. It’s like going into battle.


By decoding the truth, Coller said people will gain power and courage in their lives. However, he stressed that those seeking the truth, must also be prepared to handle the outcome. If someone isn’t ready for that step, Coller suggests throwing the CD out the window.

“You have to ask yourself, how am I going to deal with it?,” he said. “Are you going to get a divorce (if you learn the truth about your spouse’s lying) and do you have an attorney ready? This is only for those ready for the truth.”

Coller urged teachers, parents, employers, spouses, business associates, senior citizens and anyone else who questions the truth to purchase a CD and visit his Web site at The CD is also available for purchase on Amazon and iTunes.


Civilian lawman open constable/PI firm in Lynn, MA

LYNN -- Chances are that if longtime Peabody constable and private investigator Michael A. Coller pays you a business visit, you're not having one of your better days.

But last Friday was indeed a terrific day for the civilian lawman with his 20 years of experience in the legal arena to launch a new venture, MAC Investigations.

City officials including Mayor Judith Flanagan Kennedy and State Sen. Thomas McGee, along with Wyoma Square business owners and friends in the legal community, gathered for a ribbon cutting to welcome Coller at his new business office. Coller plans to steadily grow his business specializing in process serving and evictions, private investigation, corporate security services, vehicle repossession, property management and notary services.

Coller brings more than 20 years experience as a leader in corporate security, having worked for several major retail chains, handling firearms background checks, loss prevention services and internal investigations. The Saugus native an 1985 Saugus High School graduate lives in Peabody today and he was licensed by the State Police as a private investigator and was sworn in as constable in Essex county just last year.

With his corporate security expertise, Coller was able to skip the usual year of apprentice or tech training required to become a PI.

"I was trained in interrogation 20 years ago," he said. "I've had a great career in corporate security, but the time was right for me to go off on my own," he said.

Coller takes on all types of private investigation work and is authorized by the Commonwealth of Massachusetts Committee for Public Counsel Services to provide investigative assistance for public defenders.

"It's not all glamorous as it's often portrayed on TV or in movies," Coller said. "It can be long hours of monotony" to complete an investigation, he added.

In addition to private investigations, Coller aims to provide corporate security consulting and personal security services. He is also a security vendor for the Massachusetts Film Office, he hopes to build on work he has done in the past to provide security for major movie production sets in Massachusetts.
