Criminal Defense Investigations Success Stories

Highway Betrayal

South, Not West
The subject departed his residence and immediately headed in the wrong direction—not toward his claimed destination, but south into Texas. We contacted our client immediately with the devastating news. Hours later, he arrived at a South Texas hotel, nowhere near his stated business meeting location. Shortly after checking in, an unidentified woman exited the hotel with him. They drove to a local steakhouse for a two-hour dinner—intimate, comfortable, clearly not strangers—before returning to the hotel room together. We provided our client with the exact hotel and room number. She made the painful decision to see for herself, arrived late that evening, gained access to the room, and confronted them both in bed. The truth she feared became the truth she needed.

The Hidden Life

Seven Days of Documented Deception
Vehicle registration searches led to multiple addresses, but initial surveillance found no sign of the subject. Phone calls claiming to be “at work” had silent backgrounds—no construction sounds, no machinery. Day six brought the breakthrough: 12:30 AM surveillance located the subject’s vehicle at a north Houston residence. Later that day, she visited an unfamiliar address our client had never heard of, staying one hour before leaving. Morning surveillance on day seven confirmed she never departed for work. The job claims were completely fabricated.

Airport Rendezvous

Terminal C and the Truth
August 23, 4:47 AM: The subject’s truck backed out of the driveway. Our team was already in position.
The subject drove straight to Bush Intercontinental. Terminal C arrivals.
6:12 AM: A woman emerged from baggage claim. A young boy beside the woman.
The embrace wasn’t friendly. The kiss removed all doubt.
The woman slid into the middle seat—not passenger side. The boy climbed in back.
The Chase: At the first red light, more kissing. At the second, the subject’s arm around the woman.
Then the subject spotted us.
The truck hit 65 in a 45 zone. Weaving through traffic. Running.
7:04 AM: Gas station stop. The subject photographed every vehicle in the lot—including ours.
Game over. But we had what we needed.
