UPDATE:
I talked to the Brewer Police Officer this morning.
Kenneth Dorr Sr. is the old man living at 65 South Brewer Drive with his wife.
Kenneth Dorr Sr. has a son, named Kenneth Dorr Jr.
Kenneth Dorr Jr. is a convicted felon.
When the Brewer Police Officer initially went to the 65 South Brewer Drive address, on 10 March, both Kenneth Dorr Sr. and Kenneth Dorr Jr. were at the house. Both men denied knowledge of the situation involving the scam.
On the morning of 11 March, Kenneth Dorr Sr. contacted the Brewer Police Officer and informed the officer that a check in the amount of $1230 from USAA had been deposited into his account last week on 4 March. This is the check that I sent "Kenneth Dorr". Kenneth Dorr Sr. actually went to the bank on 11 March and got a copy of the check that was deposited and provided it to the Brewer Police Officer. He also informed the officer that he would withdraw the money and send it back to me. For now, the officer asked him to wait until he verified all of my information with the police report that I filed in my town.
I talked to the Brewer Police Officer this morning, 11 March, and he provided all of this information to me. At this point, I am waiting for the Brewer PD to talk to my local PD, square everything away, and move forward. It looks like I will get my money back (no guarantee, but a good chance) and that the Police Department is going to try to put together enough evidence to find the actual perpetrator. Part of this evidence will be trying to pinpoint the scammer using IP addresses.
I think it's the son...you'd have to provide strong evidence for me to believe otherwise at this point. Thanks for all of the encouragement and support through this. I will continue to provide updates until this is settled. I would also be more than willing to speak with anyone directly who may have been scammed by this guy. Two other users on here have already reached out to me that were scammed by this guy.
