(yes, I read the entire investigation part of the affidavit)
According to Brian Hogan's room mate (pg 14) an "intoxicated male" gave him a phone believing it was his. Hogan remained at the bar "a little while longer" and no one claimed the phone.
According to Powel (the employee who lost the phone) (pg 16) he states his last memory of the phone was placing it in his bag and then placing the bag by his feet.he was there till closing at 11:00 PM local time. He left when the restaurant started to close and he thinks the phone could not have remained in the restaurant more than 15 minutes.
Brian's room mate called the police because the phone was synced to her computer and Hogan's and was afraid law enforcement could get the ip address and trace it back to her (pg 12). So she was calling to absolve herself from legal issues. Also when she was shown the phone it appeared apple may have already done a remote wipe of the phone.
George Riley says (pg 12) that the phone was invaluable and that the $8500 (yes, supposedly he got $8500 total, no source on the other $2500 though) that Hogan got the phone was worth the price of the phone if not more.
Brian Hogan and someone else (sorry, I'm getting tired of finding this in the pdf) knew the police were investigating and was in the process of destroying/hiding evidence. The police went to hogan's father's house and found Hogan with his girlfriend. He said that the other person had some of the evidence. Eventually they got a hold of him and he placed the other items in front of a church.
Only other gem I found in there is a quote as stated by brian's room mate when she urged him not to sell the phone as it would ruin Robert Powel's image he told her "Sucks for him. He lost his phone. Shouldn't have lost his phone"
