The Department of Homeland Security said the 23-year-old was shot after intentionally hitting an agent with his vehicle on South Padre Island.

Prosecutors say a grand jury has rejected indictments over the fatal shooting last year of a U.S. citizen by a federal immigration agent during a traffic encounter in Texas.

The involvement of federal immigration agents in the fatal shooting of Ruben Ray Martinez on South Padre Island in March had not been disclosed in initial reports.
