Zapata, Texas (CNN) -- The wife of an American man missing since a reported pirate attack on a U.S.-Mexico border lake said Thursday that she might take a lie detector test if people continue to doubt the veracity of her account.
If "that's what the authorities think I need to do, then that might be an option," Tiffany Hartley said when asked on CNN's "AC 360" about taking a lie detector test.
Hartley was on several CNN shows Thursday recounting what happened last week on Falcon Lake. She also talked about her feelings about people doubting her account of the alleged attack.
Tiffany Hartley told authorities her husband David was shot and killed by pirates on Falcon Lake during a sightseeing trip. His body has yet to be found, leading to questions about the accuracy of her statements.
But Hartley told HLN's "Issues with Jane Velez-Mitchell" on Thursday that "I know what I know".
"It's hard being judged and thought of that I might have done something to him," she said. But she added, "As long as I know the truth, God knows the truth. And other than that, it almost doesn't really matter to me, because I know what happened that day".
Mexican authorities said earlier this week that they could not verify the shooting, and Hartley was asked point-blank on NBC's "Today" show Wednesday whether she had anything to do with her husband's disappearance.
