The builder got up every morning long before dawn, left home to pick up his construction crew and then headed out to work on yet another house somewhere across the sprawl of Houston.

Fourteen hours later, Lorenzo Salgado Araujo would return to the wife he’d met as a teenager in Mexico and the modest house he’d built for his family on the city’s east side.

It’s what he’d done for decades, according to Ronaldo Salgado, his oldest son. He said his father built hundreds of houses over 35 years, creating a life for his family and watching as his three sons headed off to college.

On Tuesday, a U.S. Immigration and Customs Enforcement officer fatally shot Salgado Araujo, 52, after he was pursued by federal agents driving unmarked vehicles while he was taking his crew to their latest job site. The shooting has outraged Houston leaders and renewed public scrutiny over ICE and Trump’s immigration crackdown.

Four Democratic members of Congress who represent the Houston area said at a vigil Saturday that they would push for an independent investigation into the shooting.

“We are never going to forget that his blood is on Donald Trump’s hands,” Rep. Christian Menefee said. “We are not at war. Lorenzo Salgado Araujo was not a casualty. He was a human being who was murdered by our government.”

Federal agents were looking for someone else when they tried to stop Salgado Araujo’s white van, Democratic U.S. Rep. Sylvia Garcia said, citing a briefing she received from ICE’s acting director. The Department of Homeland Security has said an ICE officer fired at the van in self-defense after Salgado Araujo, who officials described as an “illegal alien,” rammed an ICE vehicle. They have provided no evidence.

The three men that Salgado Araujo was driving said he was shot through a passenger window and that the ICE officer who fired was not in front of the van or even in danger, a lawyer who has spoken with them said Friday.
