Sorry no link, but evidence so far indicates:
AH wrecked her car 6/06.
We know through KC and AH text messages that this car was towed to AL's apartment parking lot 6/14, where KC had access to it everyday from 6/15 on. On 6/19, KC texted AH "Call me when you're going over to see your car" and AH texts back "On my way." KC needed to know when AH would be near the car so she could either retrieve evidence and/or Caylee from AH's car prior to AH seeing the car, or to know when AH left the car again, so it would be "safe" to place (or replace) Caylee and/or evidence there. AH's father was supposed to pick the car up to repair the first weekend in July.
There was a second car referred to in the LE interview with WW interview, that had been wrecked, brought in for repair and "smelled like a dead body" as per the crime tip LE received. This could not have been KC's car because she abandoned her car 6/27 and she had not yet met WW. KC's car's whereabouts are accounted for from 6/27 on; Amy's is not.
LA "took care" of AH's key, which is stated in his interview with LE. He laughs with LE when describing the smell coming from KC's car the night of July 15 and makes an odd statement to officers that was the
First time he smelled it. He found the key on KC's key ring July 15th and knew it was a car key. I think he spent part of his 2.5 hour absence away from the As home that night gathering KC's belonging's from TL's apartment and trying to locate AH's car in the parking lot and that KC hinted to him to look bottom left. TL's apartment number is #210, upper floor, something is to the bottom left of his apartment. I think LA smelled decomp for a
second time in AH's car later that same night.
