This affair seemed to be common knowledge from the get-go. We just could not discuss it here, due to the rumor factor. But yes, supposedly CL was gone until the 30th. RUMOR OF COURSE!! And I have no idea if NL was ever with him during that time, but supposedly she was home when the detectives came on the 29th and CL was not. But think about it, it is routine for detectives to interview neighbors to see if they saw Erin leave that morning etc.....Clarifying: I think the initial interview on the 29th was a routine "check with the neighbors to see if they saw anything" type deal. CL was not there, NL was. It had to be later that they interviewed CL (probably found out about affair) and his story had inconsistencies. This still leaves the 29th open with no alibi for CL.
