She had a fake gun in the car, which she was pointing at other motorists, which prompted the first calls to 911.
After a number of miles, she was stopped on Loop 820, and police found several pipe bombs in the car. They closed down the freeway and detonated them. I didn’t see the explosions myself, but I have friends who did, from miles away. No telling what she was planning to do.
Wow...thanks!
