Austin police Officer Coleman Martin, 29, is facing a Class A misdemeanor charge of “false report” as a result. A year ago, Martin received a Life Saving Medal from the Police Department after he found and then administered CPR to a man who overdosed on heroin in February 2016 in Northwest Austin.

According to an arrest affidavit for the missing officer, a woman who isn’t Martin’s wife shared an email with detectives, in which Martin wrote to her and said his plan for a staged death had been successful.

The affidavit doesn’t say how the woman knows Martin.

Martin’s email to the woman said he had staged the scene by parking his vehicle by a body of water near the U.S. border with Mexico, the affidavit says. He then rode a bicycle for about eight miles to a convenience store, took a taxi to the border and took a bus farther into Mexico, according to the email described in the affidavit.
