Thanks for clarifying. I have been intrigued with LD as a potential suspect and if he truly has the alibi that he claims (and likely is true because it can easily be checked), I'm disappointed that he can prove that he wasn't in the area. If he, indeed, can absolutely prove with a strong alibi that he wasn't in the area that night.
I have known of a case where the perp could prove they were 200 miles away and in another state the night of a murder. But, it turned out that he checked into a hotel that was 200+ miles away from their home, then immediately went back to murder his wife, and then returned to the hotel by early morning hours. This was years ago and the perp didn't take into account cell phone pings, so that was problematic for him. And, the hotel had footage of him leaving and returning in a side door of the hotel and digital evidence of him leaving and returning to his hotel room with his key being recorded at the times of entry and exit.
FBI had enough evidence linking him to NG's disappearance that a federal judge approved a federal warrant to search his house. A federal warrant has a fairly high bar so while he may not be the actual perp, I'm still curious about his possible involvement. Maybe there will be evidence in his Road Runner that the FBI took in for testing.
