A sheriff in Texas has certified that migrants flown from Texas to Massachusetts were victims of a crime and eligible for special visa privileges.

Texas’ Bexar County Sheriff Javier Salazar announced Thursday he has filed certification designating dozens of migrants flown to Martha’s Vineyard from Texas as victims of a crime. 

“Based upon the claims of migrants being transported from Bexar County under false pretenses, we are investigating this case as possible unlawful restraint,” Salazar said in a statement.

“We have submitted documentation through the federal system to ensure the migrants’ availability as witnesses during the investigation.”

The certification can be used to solicit special visas available only for noncitizen victims and witnesses to crimes, according to immigration lawyers in the area.

In September, Florida Gov. Ron DeSantis sent 48 migrants to Martha’s Vineyard, a luxury beach town off the coast of Massachusetts, and was blasted by Democrats and former presidential candidate Hillary Clinton, who called it a form of “human trafficking.”

Salazar previously announced the opening of a criminal investigation in relation to the flights from Texas.

However, Salazar is not alone. DeSantis’s enthusiasm for transporting illegal immigrants to more liberal “sanctuary cities” in the northern states has drawn the ire of political opponents at all levels of government.
