Tiffany Hartley, whose husband was shot while the two were fleeing from Mexican pirates on jet skis earlier this month, said the attack should be an example for President Obama on the need for more border security.
"He should wake up and look at what's going on in our backyard," Hartley said, referring to the pirates that attacked her and her and her husband on Falcon Lake at the Texas-Mexico border.
Speaking outside of her home in LaSalle, Colo., Hartley said she spent 16 hours speaking with Mexican officials, who, in a rare move, came across the border to meet with her.
"I think the only reason they did is A, I was not going over there. And B, [because] of the publicity they've had," she said.
"But no, I don't live in fear for my life," Hartley said. "David and I didn't live in fear. And that's how I am living."
Hartley said she plans to remain in Colorado for the time being to relax at her family's 20-acre ranch, but wants to use the media to help keep the case in the spotlight.
"Being here in Colorado, you guys are, you're going to be my way to get my voice out," Hartley said.
Mexican authorities have said they will press their search for David Hartley's body after the lead investigator, Rolando Flores, was decapitated on Oct. 12.
"I still believe they are going to do what they can for David and for us, for bringing him home," Tiffany Hartley said two weeks ago,
Hartley said she had met with Flores, the head of state investigators in Ciudad Miguel Aleman, and that he seemed to be working hard to find her husband.
"I can't even explain how my heart is just broken for him and his family. There aren't any words," she told "Good Morning America" two weeks ago. "He was just such a nice guy and he really wanted to do what he could for us."
U.S. authorities, however, are worried that the beheading of Flores will cause Mexican police to back off the murder investigation.
"We know that's a possibility, but we haven't heard any word that's going to happen," Tiffany Hartley said. "Obviously we want David to be found and we don't want them to stop their search."
The widow said she gets search updates from Mexican authorities almost every day.
Zapata County, Tex., Sheriff Sigifredo Gonzalez said he felt for Flores' family.
"They're going to now be without a father, without a husband when in fact all they were trying to do was search for the body of Mr. Hartley," Gonzalez said.
Flores' severed head was delivered in a suitcase to a military post near the border with Texas. His wife had said he was working late on the Hartley case the night before and never came home.
Though many believe Flores' murder was the work of the drug cartels who control the waters where Hartley was killed, Mexican authorities have denied his death had anything to do with the murder investigation.
Hartley was shot September 30 while on the Mexican side of Falcon Lake. Tiffany Hartley said the two were headed back to the American side of the lake on jet skis when they were chased by Mexican pirates. She told authorities that her husband was shot in the head and that she had to flee to shore to save her own life.
Hartley has said she has been asked by Mexican authorities to travel to Mexico to give a statement, but she has declined to protect her own safety, instead filling out paperwork at the Mexican consulate.
