At about 4:10ish, paramedics were just getting there.
From what rubbernecking I cared to do, looked like an old geezer in a Ford Escape probably forgot which pedal was the brake. It looked like he plowed into the back of a newish Jeep Cherokee, which pushed it into the back of a Ford Contour. Both ends of the Jeep were smashed pretty bad. The front of the Ford was pretty much gone too. There was a van stopped too, so the Contour may have tagged a 4th car.
Down to one lane, traffic starting to back up, yadda yadda yadda
