Today, a jury of 12 women and 4 men from Montgomery County will hear the case against Woodmore bus driver Johnthony Walker.

Walker faces six counts of vehicular homicide, seven counts of assault and 18 counts of reckless aggravated assault in the 2016 Woodmore bus crash that claimed the lives of six children.

9:52am - CARRION: It's important for you to know that General Pinkston and I say that Walker didn't do this intentionally. This is not that kind of case. What we are saying, is on Nov. 21, 2016, Walker had a lot of choices, chose to be reckless and chose to be on the phone and speed.

9:42am - CARRION: Six sets of parents have kids who will not come home. The 31 surviving kids will live with bumps, bruises, amputated limbs, fractured spines. It all could have been avoided if Walker would have slowed down and done the speed limit and stayed off his phone.
