In the unedited interview Deorr sr said after searching 20 min or so they called for help. Then after that he said it was around 2 when they left him with GGP.
So idk. Its hard for me personally to take anything as fact at this point unless if its coming directly from someone who was there or LE. I mean unless if I hear the parents them self say something different then their story hasn't changed.
This article, published July 12th, the day before their interview, says DeOrr disappeared about 1:30. JM told 911 dispatch at 2:36 that he had been missing for about an hour. Everything (to me) seems to indicate DK just misspoke when he said 2:00.
