She then sent a text message and called him again, leaving a voice message when he didn't answer.
The statements about inheritance, still loving him and buying a house were on the message, according to the agent's affidavit.
The court documents identify the man only as John. That is not his real name, The Oklahoman has learned. He reportedly resides more than 200 miles from Mustang.
The agent did not disclose whether Keith Bryan found out about the affair. He and his wife were married more than 30 years. She filed for a divorce in January 2010 but then took no further action in the case.
Among the items seized Oct. 7 from her work, a Mustang real estate office, was a file folder containing printed emails and hotel reservation information. Also taken into evidence at the office was a Mustang Flowers and Gifts card made out on Valentine's Day 2011 “to Becky Bryan from Keith.”
Her attorney, Gary James, said Monday night that he wanted to review the affidavits and talk to her before commenting.
