Tiffany Hartley spoke out on CNN's "AC 360" Monday night, pleading with whoever might have information as to the whereabouts of her husband, who she says was shot while the pair were sight- seeing Sept. 30 on Falcon Lake.

"I plea [sic] to the people who did this...To anybody who knows who did this," Hartley said on the program. "Just give me my husband back. I want to take him home and honor him. And I am sure somebody out there knows. Just help me bring my husband home."

Prior to Monday's appearance on CNN, Tiffany Hartley spent more than eight hours with federal and state authorities in Mexico recounting  what happened the day she says her husband was shot.

She reportedly said they were headed to Falcon Lake early that morning to "enjoy a day on the lake"; however, when the pair crossed over into Mexican territory to see a historical church there they were confronted by three boats and gunmen, reports CNN.

The gunmen, whom authorities believe are linked to a Mexican drug cartel, opened fired and allegedly shot her husband. She claims she attempted to load her husband onto her jet ski.

Mexican authorities suspended the search for the slain American after the lead investigator in the case was beheaded.

"Mexican authorities told the U.S. Consulate that the suspension of the search was only temporary and would continue at a later date," Brian Quigley, a spokesman for the U.S. Consulate in Matamoros, Mexico, told CNN. "We are going to hold them to that."
