(MEXICO) -- The wife of a man allegedly killed by pirates on a lake that straddles the U.S.-Mexico border will return to FBI offices Monday to resume a marathon session of questions from Mexican authorities.
Tiffany Hartley, wife of David Hartley, who is missing after the jet ski incident Sept. 30 on Falcon Lake, endured eight hours of questioning by Mexican investigators Friday. She has said she refused a request to come to Mexico for further questioning, out of fear of a possible arrest.
"I just don't think that's a wise decision," Hartley told ABC News. "I think they do believe my story, but I don't know what their plan is -- why they need me to go over there when I've signed every document they told me."
When asked if she feared arrest on the Mexican side of the border, Hartley said, "possibly."
Hartley said that she hopes that by speaking to investigators without an attorney, she can convince them to continue their search for her missing husband. The search was called off last week after a lead investigator for the Mexican authorities was beheaded, allegedly by members of a drug cartel.
David Hartley was last seen when Tiffany said he was shot by Mexican pirates while the couple rode jet skis on the Mexican side of Falcon Lake. In a heart-wrenching 911 call, a seemingly panicked Tiffany explained to the dispatcher that David was shot in the head and that she was not strong enough to pull his body onto her jet ski. Neither David's body nor his jet ski have been recovered.
