BEXAR COUNTY, Texas (WFLA) — A Texas sheriff has opened an investigation after nearly 50 migrants were flown to Martha’s Vineyard.

The Bexar County Sheriff’s Office said the migrants were “lured from the Migrant Resource Center, located in Bexar County, and flown to Florida, where they were ultimately left to fend for themselves in Martha’s Vineyard.”

The sheriff’s office said it is working with private attorneys who are representing the victims as well as advocacy organizations.

“We are also preparing to work with any federal agencies that have concurrent jurisdiction, should the need arise,” the sheriff’s office said.

“I believe there is some criminal activity involved here,” Sheriff Javier Salazar said. “But at present, we are trying to keep an open mind and we are going to investigate to find out what exact laws were broken if that does turn out to be the case.”

The Associated Press reported that Gov. Ron DeSantis’ office responded with a statement that said the migrants had been given more options to succeed in Massachusetts.

“Immigrants have been more than willing to leave Bexar County after being abandoned, homeless, and ‘left to fend for themselves,” DeSantis spokesperson Taryn Fenske said. “Florida gave them an opportunity to seek greener pastures in a sanctuary jurisdiction that offered greater resources for them, as we expected.”

Salazar said the migrants had been “preyed upon” and “hoodwinked,” the AP reported.
