A Texas police officer who was originally reported missing is believed to have attempted to fake his own death and to have fled to Mexico, officials said Friday night. >> Read more trending news Austin police Officer Coleman Martin, 29, is facing a Class A misdemeanor charge of “false report,” as a result. Martin’s wife told KVUE-TV on Saturday that “Cole recently received a new prescription medication.' 'The side effects were causing him to be depressed and think irrationally,” she said. “We want him to know his family loves him unconditionally and wants him home safe.' Martin’s wife asked to remain anonymous for the interview. An arrest affidavit for the missing officer said a woman, who was not his 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 does not say how the woman knows Martin. Martin’s email to the woman said he had staged a scene by parking his vehicle by a body of water near the U.S. border with Mexico, the affidavit says. Then he rode a bicycle for about 8 miles to a convenience store, took a taxi to the border and rode a bus farther into Mexico, the affidavit says he said in the email. Police obtained video footage of Martin at a gas station in Del Rio, the affidavit says. They also talked to a clerk at the gas station who had spoken to Martin. Martin told the clerk he had biked from Amistad Park to the store, the affidavit says. Police first got involved on Tuesday night, when Martin’s wife called 911, the affidavit says. She told police that Martin had texted her a photo of a handwritten note that said he was going to drown himself in a lake near the border of Mexico. The next morning, officials at the Amistad National Recreation Area said they found Martin’s vehicle with a suicide note inside, the affidavit says. His wallet was also inside the vehicle, but there was no money inside it. His passport was also not in the vehicle. In response, “a massive search operation was initiated using local, state and federal resources” on Wednesday and Thursday, the affidavit says. The search team found an inflatable raft in the Amistad Reservoir, which is on the Rio Grande at the border between Mexico and the United States, with Martin’s name, his date of birth, date of death and his and his wife’s initials written on the side, the affidavit says. Inside the raft were remnants of a concrete block as well as scrape marks that indicated that concrete blocks had been pushed over the edge. Investigators discovered a charge on Martin’s credit card for a new HP tablet from a Best Buy in Austin a few hours before he sent the suicide note to his wife, and the tablet was not found in his vehicle, the affidavit said. Then, investigators learned that someone had accessed Martin’s email from Mexico about five hours after he sent the suicide note text. According to the affidavit, investigators believe Martin placed “the boat to appear he entered the water, paddled to the middle and jumped overboard with concrete blocks and ropes, and (placed) the raft on the shore to give the appearance it had drifted to shore from where the initial entry place was.” Investigators tracked down and interviewed the unnamed woman at 4:15 p.m. Thursday.
