The incident sparked protests in Houston on Wednesday, with four Democratic members of Congress demanding an independent investigation into Salgado’s death.

In a letter to DHS, Representatives Sylvia Garcia, Al Green, Lizzie Fletcher and Christian Menefeewrote wrote that the incident was “not the first time ICE agents have used unnecessary and deadly force.”

They urged Senator Markwayne Mullin, head of the Department of Homeland Security, not to forget the cases of Renee Good and Alex Pretti, two American citizens killed by federal agents in Minneapolis in January.

Referring to the Salgado shooting on Tuesday, they wrote that “instead of answers and accountability, DHS and ICE issued a statement that echoes the same stories we have heard before, alleging evasion of arrest, use of a vehicle as a weapon, and that the fatal shooting was the result of self-defense.”

In the wake of the shooting, the Mexican government said it would file criminal complaints in the United States over the deaths of more than a dozen of its citizens in U.S. custody.

Mexican Foreign Minister Roberto Velasco said 14 Mexicans had died while in ICE custody and another three during ICE “arrest operations.”

Velasco said he had received instructions from Mexican President Claudia Sheinbaum to file the complaints and that his goal was to have deaths of Mexicans in ICE custody or operations investigated “as criminal matters.”
