 A Texas detective is dead, shot early this morning at what authorities are calling an ambush. It all started last night at a Little Caesars Pizza in northeast Houston, where a customer, upset that his order was wrong, allegedly pulled a gun on an employee, pistol-whipped him, and then fled in a vehicle. The unidentified Harris County detective reported he had found the car. The detective was found shot to death. The suspect's still on the loose, but investigators say they think they know who he is.
