CR was prowling around Brooklyn. He saw Mollie, who he had seen jogging before, and drove around the block a couple of times until he got up the nerve to pull up next to her. He rolled down his window and said something crude (blowing kisses, hi hottie, whatever). She either ignored him, said please leave me alone, or started running away. That triggered him and he got angry - he felt disrespected. He drove along in the car up E 385 behind her while she's trying to run away until they were a little out of town, pulled over, jumped out of the car, grabbed her from behind and pushed her to the ground slamming her head and choking her. I think he threw her in the car and drove down to the cornfields, assaulted her, and then left her there covered.
