Texas trooper issues stark travel warning to Americans after three women vanished crossing the border to visit a flea market - More than 550 U.S. citizens are now missing in Mexico

A Texas trooper is warning Americans to rethink traveling to Mexico after three women vanished when crossing the border to sell clothes at a flea market - joining the more than 500 US citizens currently missing in the country.
Lieutenant Chris Olivarez, of the Texas Department of Public Safety, told travelers gearing up for Spring Break to be careful when planning vacations to the popular travel destination.
'Our department is urging anyone traveling to Mexico, especially spring breakers, to avoid those areas, because right now it is too dangerous with the increase in violence and kidnappings in Mexico,' Lieutenant Olivarez told Fox News. 'I can't express enough to those thinking about traveling to Mexico, especially to spring breakers...to avoid those areas as much as possible.'
The warning comes after two sisters Maritza Trinidad Perez Rios, 47, Marina Perez Rios, 48, both of Peñitas, and their friend, Dora Alicia Cervantes Saenz, 53, went missing on February 24.
Officials said they were traveling in a green mid-1990s Chevy Silverado to a flea market in the city of Montemorelos, in Nuevo Leon state - around three hours from the border - and never returned. Peñitas is just a few hundred feet from the Rio Grande River.
It comes after the highly publicized case where four Americans were abducted by a cartel after traveling into the country for a tummy tuck. Their abduction was caught on video last week and received an avalanche of attention. But the fate of the three women, who haven't been heard from in about two weeks, remains a mystery.

The sisters' cousin Ludy Arredondo wrote on Facebook that they 'do not have a single piece of news [and] the authorities do not say anything,' as she and others continue to pray for their safe return.

'They do not have clues,' she wrote. 'PLEASE do not leave us alone.

'My cousins and their friend are women, workers, responsible, mothers of their children, noble, simple women, they are WOMEN WHO WENT TO WORK. PLEASE friends post [and] share,' she begged.

The last to hear from the women was one of their husbands who spoke to her by phone while she was traveling in Mexico. He later reported them missing after growing concerned when he couldn't reach her afterwards, the Peñitas Police Chief Roel Bermea said.

'Since he couldn't make contact over that weekend, he came in that Monday and reported it to us,' Bermea said.

Officials at the state prosecutor's office said they have been investigating the women's disappearance since Monday. Beyond that, officials in the US and Mexico haven't said much about their pursuit of the three.

The FBI said Friday it is aware that two sisters from Peñitas, a small border city in Texas near McAllen, and their friend have gone missing. Bermea said their families have been in touch with Mexican authorities, who are investigating their disappearance.

The three women are among a startling 550 Americans who have been reported missing in Mexico, according to public records. This is a small part of the total 112,000 people missing in the country - and is a tiny percentage of the millions of US citizens who travel to Mexico every year for vacations and work.

But many relatives of the Americans still missing are asking why their loved ones haven’t been given a higher priority by Washington like the recent kidnapping.
