How to do a background check like a pro — it could save you money … and much more · CNBC

During the most chaotic days of North Dakota's shale oil boom, James Henrikson seemed like a reliable bet.

Thirty-two years old and exuding charisma, Henrikson had something everyone wanted during those go-go days in 2006. At a time when half the battle in North Dakota was getting workers, equipment and oil from place to place, Henrikson owned a trucking business — Blackstone Trucking.

Kristopher "KC" Clarke, an old motorcycle racing buddy of Henrikson's from Washington state, agreed to sign on as operations manager. Then a few years later, when Henrikson decided to branch out into oil drilling, he took on a partner — construction contractor Doug Carlile.

But in a story told on the next episode of CNBC's "American Greed," Clarke and Carlile would end up dead — extreme examples of the danger of not doing a proper background check, which in Henrikson's case would have turned up multiple arrests for assault, drugs, weapons violations and fraud.

Today, Henrikson is serving two life sentences at the federal Supermax prison in Colorado, convicted on 11 murder-for-hire counts.

New York private investigator Brian Willingham, founder of the Diligentia Group, says no matter how well you think you know a person, once the relationship moves to a position of trust, you need to protect yourself.

"Anytime there's a lot of risk, whether it's financial, personal, you might want to look into somebody's background to see if there's any potential red flags that you may identify about what they've done in their past," Willingham said.

But that does not have to mean hiring an expensive private eye. Willingham, a private investigator with more than 15 years experience and a Certified Fraud Examiner, shared some of his secrets exclusively with "American Greed."

Sometimes there is no substitute for some good old-fashioned legwork. That may mean going to the local courthouse to see if the person has a criminal past.

"Criminal history is one of ... the basic steps to determine whether somebody or not has any issues in their past," Willingham said.

It may seem intimidating at first, but most court documents are public records, and you have every right to see them. Of course, it helps to know what you are looking for. Willingham says many states have central repositories where you can search for criminal records. In many states — and the number is increasing all the time — the records are available online. So you can start at the state level and see if you need to make a trip to the courthouse.

Willingham says beware of commercial web sites that claim to allow you to do a complete background check — one-stop shopping — for a price.
