Ms. Herrera’s lawyer, Calixtro Villarreal, declined to be interviewed on Saturday. The Starr County district attorney’s office and sheriff’s office could not be reached for comment. In his statement, Major Delgado said the district attorney planned to release details to the news media on Monday.
While women have been arrested, jailed and convicted in cases involving self-induced abortions, including cases in which women have used drugs during pregnancy, such cases have been rare and have even more rarely resulted in conviction.
But that could change in this new political climate, as women increasingly turn to self-induced abortions, said Stephen Vladeck, a law professor at the University of Texas at Austin.
“States have made it that much harder for women to obtain abortions from medical professionals, leading them to the more dire remedy of doing it themselves,” Mr. Vladeck said. He added that “these kinds of prosecutions that would have been incredibly unpopular and controversial as recently as 10 or 15 years ago” are now receiving more support.
Jenny Ecklund, a lawyer representing the Frontera Fund and other abortion rights groups in Texas, said that the indictment sent a distressing signal to women in the state. “If a state can criminalize conduct that they neither know nor understand, it puts the lives of anyone who can be pregnant in the state of Texas in real danger,” she said.
