I'll also say this. If CR was seen on video, helping, carrying etc. Lauren down the street to North Townhouses, then why didn't he just help her to her apartment at Smallwood where she lived?
She lived on the fifth floor, and CR got beat up on the fifth floor elevator lobby, so clearly he wouldn't go back there.
Why did she leave with him instead of going to her apartment-maybe she didn't want to stop partying just yet?
