The Texas Rangers say they have not been asked to investigate the fatal shooting of Lorenzo Salgado Araujo by a federal ICE agent and are not involved in the case.

The letter came after a group of Houston-area state lawmakers wrote to the Texas Department of Public Safety urging the agency to open a parallel investigation into the shooting, which killed Salgado Araujo in the Magnolia Park neighborhood while he was on his way to work.

"DPS has not received a request from any federal agency or official to investigate the officer-involved shooting of Lorenzo Salgado Araujo and is not participating in that investigation at this time," the agency said in its written response to lawmakers.
