Bobby Baker, DISD Superintendent said, "Suddenly word was getting out that we're in lock down. Lock down can be used many different ways. We had just security of doors and those type things on campuses."
Baker says he took these steps just to be careful. He was concerned the missing teenager would cause some type of mischief at the school, like maybe pulling a fire alarm. But when students and teachers saw the doors being locked, and the extra security, rumors started spreading.
As these rumors passed from person to person, they grew from a simple situation with a runaway, to somebody having a gun at the school, to shots being fired. It progressed to the point where many parents started calling the district to make sure their kids were safe.
Baker said, "It really didn't become disruptive until the word began to get out."
