>> just am i going to get out. if i do, what will happen afterwards. >> reporter: mrs. powers, talk about where you heard, what you saw when you first heard from your son. >> i was on a conference call. i actually got texted by one of my co-workers that said there was a shooting. they immediately said two people had been shot but i literally dropped all my devices, grabbed my keys and got in the car and drove here. i live in cherry creek. i was bawling the whole way here. i didn't actually get any communication from the school on my phone, which made me more nervous. then i kept texting my son but he didn't respond. so you keep thinking the worst. then he finally was able to ping me in instant message and let me know he was okay. i frantically drove here, parked the car, ran to the yellow tape to get him. >> reporter: deb has a question for you. >> i just wanted you to ask him what the security measures are like there at arapahoe high school when they go in every morning. >> reporter: okay.
