The immigrant does not appear on a list of people sent to a prison in El Salvador, and his family and friends have no idea of his whereabouts. He has essentially disappeared.

In late January, Ricardo Prada Vásquez, a Venezuelan immigrant working in a delivery job in Detroit, picked up an order at a McDonald’s. He was heading to the address when he erroneously turned onto the Ambassador Bridge, which leads to Canada. It is a common mistake even for those who live in the Michigan border city. But for Mr. Prada, 32, it proved fateful.

The U.S. authorities took Mr. Prada into custody when he attempted to re-enter the country; he was put in detention and ordered deported. On March 15, he told a friend in Chicago that he was among a number of detainees housed in Texas who expected to be repatriated to Venezuela.

That evening, the Trump administration flew three planes carrying Venezuelan migrants from the Texas facility to El Salvador, where they have been ever since, locked up in a maximum-security prison and denied contact with the outside world.

But Mr. Prada has not been heard from or seen. He is not on the list of 238 people who were deported to El Salvador that day. He does not appear in the photos and videos released by the authorities of shackled men with shaved heads.
