2004 Abilene High graduate, David Williams Junior, was believed to be in the building at the time the shootings took place.

He is an E-5 sergeant stationed in Fort Hood.

The Williams family here at home waited in shock to here from him as the tragic event occurred.

We spoke to his sister on the phone earlier today in a KRBC exclusive.

She told us about the terror of hearing about the attack, and the joy upon hearing the news that her brother was OK.
