Convicted of murdering a 16-year-old girl in 1994, Mexican national Humberto Leal was executed despite White House concerns that US citizens abroad could face harsher punishments as a result.
The state of Texas on Tuesday evening executed convicted murderer Humberto Leal, a Mexican who was brought to the US as a toddler, despite pleas from the White House, Mexico, and the United Nations to forestall the ultimate sanction.
A short time earlier, the US Supreme Court refused to order a stay of execution with a 5-to-4 vote.
The case has drawn international attention because of Mr. Leal's Mexican nationality. The White House requested a stay in part because it worried that, because of the execution, Americans could expect harsher treatment if they run afoul of the law abroad. "This case implicates United States foreign policy interests of the highest order," Solicitor General Donald Verrilli Jr. said.
