Valentine's Day is filled with love, flowers, presents and candies, but sometimes there's infidelity, cheating and lies mixed in.
Business ramps up this time of year for private investigators.
K&R Investigative Group partner Brian Reschke said about 80 percent of their cases involve cheating spouses and many of those are opened this time of year.
The game has changed over the years as better technology develops.
Reschke uses hidden cameras, cell phone software and GPS tracking which gives a nearly up-to-the-minute location of a subject.
"With the GPS tracker, we don't have the be that close. With five second updates, we can be four blocks back and not even see the target vehicle in front of us because we can pull it up on our iPhone," Reschke said.
