Private investigator says cheating men do exact same thing that gives them away

A private investigator has detailed the one thing he's noticed all men do when they are cheating which ultimately gives them away.

It can be pretty difficult to determine whether your partner is cheating, and you don't particularly want to be accusing your other half of doing the dirty if you haven't got some form of proof.

And that's where a private investigator comes in, with some people paying these detectives to help determine whether there other half is deceiving.

To be honest, there are some pretty obvious signs that someone is cheating, whether that be catching them in the act, or seeing them messaging another person in a flirtatious way on their mobile phone.

Connecticut PI Ray Ranno is thankfully on hand to provide a sign that is a little less obvious that may just be starring you in the face.

While Ranno noted stakeouts can be pretty boring, they become more interesting when he picks up on the signs, which allows him to predict on what will happen next.

Speaking on the Locked In with Ian Bick podcast in 2025, the private investigator weighed in with his expert opinion and exposed the signs to be looking out for.

A clean car is a big sign, apparently

“If a guy's going to pick up his sweetie on the side, he wants a clean car,” Ranno said.

The detective went on to state he would regularly see guys get their car all spruced up before moving ahead with their infidelity.

He continued: “As soon as somebody goes to the car wash I think ‘Ha ha, what's next?’ It’s amazing how they do that. Women not so much. Women don't do it so much because they usually jump in the guy's car, men always want to drive.

"It's very rare that I see a guy jump into a female's car.”

How he gathers evidence to expose cheaters

Ranno explained that after the pair have met, the man gets to his part of gathering evidence for the paying party.

He also dismissed the stereotypes of a guy in a fedora and massive trench coat simply taking pictures from a car.

The detective then went on to detail his rather tech-savvy gadgets he uses to catch people in the act.

A 'long-lens camera and a fake coffee cup with a HD camera inside'

Ranno noted that, while he does have a long-lens camera for picture and video evidence, he also has a fake coffee cup with a high-definition camera inside so that he can tail and observe them in plain sight.

"If I go into a coffee place, or a supermarket wherever I need to be, I just take the lid off turn it on put the cap on and it looks like I'm walking around with a coffee. Meantime I'm videotaping everything," he said.

Once all the evidence is gathered, the videos and pictures then go to the person paying him, aka the individual who believes they are being cheated on.

So, keep a vague eye on not just your partner's phone, but his car too, eh?
