Brian Pendergast was not informed of Pete's cooperation until Monday at noon. By Monday at 12:15, AFOSI Detachment 803, the Air Force Inspector General's Office, the Department of Defense Office of Inspector General, the United States Attorney's Office for the District of Wyoming, and the FBI Cheyenne Resident Agency had jointly opened a federal investigation against Sentinel Ridge Properties LLC, and the Sentinel Ridge Estates, HOA. The investigation named Briany Pendergast as a co-conspirator. Colonel Reinhomem called me at 12:30. She said, "Sir, Lieutenant Colonel Pendergast has provided complete cooperation.
Mrs. Pendergast was the front-end recruitment operative. She was personally communicating with prospective FE Warren military families and steering them to Sentinel Ridge properties at above market rents. She has been doing this for 38 months. We have her on email. We have her on text.
We have her at three open houses welcoming Air Force families personally." I asked her what she needed. She said, "Sir, the federal indictment is being drafted now. We expect it Wednesday. What we need from you, sir, is to be on your porch when Mrs. Pendergastas next escalates against your truck."
The moment she calls FE, Warren Security Forces with a fabricated jurisdictional claim, the predicate locks. I told her I would be on the porch. She said one more thing. "Sir, Mrs. Pendergast has been calling Cheyenne PD twice a week about your truck since November. She is escalating.
She does not yet know her husband cooperated. The next call she makes will be security forces. I would estimate within 72 hours. She was correct within 19 hours. Wing staff judge advocate Lieutenant Colonel Llo Shrader drove to my ranch on Sunday evening at 2100.
He brought a banker's box, a thermos of black coffee, and the kind of leather portfolio Air Force Jags have been issued at Maxwell since 1976. He sat at my kitchen table with Marray and me. He laid out the legal coordination.
