A thief wearing gloves walks into a parking lot, perhaps using the cover of night, smashes a car window and takes whats inside the vehicle, all in a matter of minutes. Its the general technique for many car burglaries, and thousands of them occur in Harris County, Texas, every year. Besides shattered glass, often theres not much visible evidence left at the scene, leaving investigators with few clues to catch the culprits. But sometimes its what investigators cannot see that helps solve many of these types of crimes.
