(Radio Iowa) – Iowa Senator Joni Ernst says she’s pressing Mexican authorities to secure the safe return of a 51-year-old Des Moines woman who was kidnapped in northern Mexico a month ago.  “Seriously, this is Mexico. This is a partner with the United States, whether it’s trade and other types of economic endeavors. This is our neighbor to the south,” Ernst said. “They need to step up.”

Chris Leguisano went missing over a month ago. She was in Mexico to deliver a truck full of belongings to a brother-in-law and was last seen in Reynosa, Mexico — less than a hour’s drive from the U-S southern border. Ernst says this is the second high-profile assault of American citizens in that part of Mexico in the past two years.

“This is a woman who was kidnapped,” Ernst said. “We can’t tolerate this.” State Department officials have briefed the staff in Senator Chuck Grassley’s office and Ernst’s staff on outreach to Mexican authorities and how U-S law enforcement are involved in the case. In July, the State Department issued a warning advising Americans not to travel to or through the state in northern Mexico that sits along the Gulf of Mexico. “It just underscores the fact that having an open border, having cartels that are running these dangerous schemes of drug running, weapons trafficking, human trafficking,” Ernst said.

Leguisano’s son told W-O-I T-V he’s gotten text messages demanding a ransom.
