CNN played an interesting phone interview with a woman and some local radio station who was a courier who had just picked up a package at the nearby medical building, who saw a car or van that seemed to be out of control and moving slowly through the parking lot, she also saw a man going into Planned Parenthood with a bundle. When the van finally came to a stop, she saw a man fall out of it, from the driver's seat, she described seeing 'holes' in his body and blood. She hunkered down in her vehicle and hid on the floor for the next several hours.
I probably left out some important stuff, but the general idea is there. It was fascinating. Maybe others heard it and can fill in the gaps?
