GEOFF BENNETT: Family members and local officials are calling for a full investigation into the shooting death of a man killed by ICE agents in Houston.

Lorenzo Salgado Araujo was shot yesterday as ICE agents tried to arrest him.

Federal officials say he tried to flee and -- quote -- "weaponized his vehicle toward an ICE officer who opened fire in self-defense."

Salgado Araujo was shot in the abdomen and taken to a hospital, where he later died.

ICE says he was a Mexican national living in the U.S.

without legal status.

His family and immigration advocates are questioning the official account, saying ICE has yet to provide evidence to support their claims.

One of his sons spoke at a news conference today.

RONALDO SALGADO, Son of Lorenzo Salgado Araujo: I am calling for a full investigation into the events that transpired yesterday -- yesterday, July 7.

He did not deserve to die.

He did not deserve to be reduced to a headline of Mexican man shot and killed by ICE.

He deserved to live a quiet life as Lorenzo Salgado Araujo, a husband, a father, and a job creator for dozens of men who also wanted the American dream.

GEOFF BENNETT: Colleen DeGuzman joins us now.

She's a reporter for The Texas Tribune.

So, Colleen, thank you for being with us.

So, DHS says Salgado Araujo rammed an ICE vehicle, that he ignored repeated commands and that he tried to run over an ICE officer.

What evidence, if any, have they provided to support their accounts?

COLLEEN DEGUZMAN, The Texas Tribune: We have received very little evidence and very little explanation.

What we do know is that ICE was in unmarked vehicles when they stopped Salgado Araujo.

And what we heard from -- today from the brother -- from the son, Ronaldo, is that his dad -- he believed that his dad would not have tried to flee from ICE, let alone run over an agent with his vehicle.

The vehicles that ICE were using were unmarked, which is the reason why his son Ronaldo believes that his dad did not know that he was being pulled over by ICE.

His dad was a construction worker and was always worried that his tools were going to be stolen.

So that's why he thinks his dad thought he was going to get robbed and why he tried to escape.

GEOFF BENNETT: Were there eyewitnesses?

And, if so, what are they saying about what transpired?

COLLEEN DEGUZMAN: We have not been able to contact any eyewitnesses or receive any video footage yet.

But, today, at a press conference with a lot of Houston local leaders, they are pressing for body footage camera and any camera footage that there is out there on what happened in Houston's East End, which is a very Latino neighborhood.

GEOFF BENNETT: What more have you pieced together about Salgado Araujo, his life, his life in Houston, and what brought ICE agents to arrest him?

COLLEEN DEGUZMAN: Those are the same questions that we have right now.

We are unsure of whether this was targeted, whether this was just a normal traffic stop.

I was at that intersection yesterday, and there was a lot of construction in that area.

And so we're wondering if this was targeted or if this was random.

But what we do know is that Salgado Araujo had three sons.

And, today, we heard from Ronaldo, who is a teacher who is a proud University of Houston graduate.

His second son is 27 years old.

He's also named Lorenzo, Lorenzo Lorenzo Jr., and he went to Tufts University, and is an engineer.

And he has at least one grandson.

He moved to Houston 35 years ago and has built a construction company here in Houston, and he's very proud of it.

He builds homes in North Houston.

And he, according to his son, was a very simple man who had a routine in the morning to get up really early.

He would pet the dog goodbye and kiss his wife, who was his high school sweetheart, goodbye before work.

And every day, when the day ended, he would sit by his porch outside to soak up the sunset.

He was a very simple man with a very strict routine.

So that's what we know about him.

GEOFF BENNETT: The president of Mexico, Claudia Sheinbaum, says that that country is pursuing legal measures.

It's not clear what that exactly means.

There are now two separate federal investigations.

We should say, though, that the mayor of Houston says the city will not conduct its own investigation while the federal investigations are ongoing.

Based on your reporting, are there calls for local officials, local authorities to do more, to uncover more, as they can?

COLLEEN DEGUZMAN: Yes.

This morning, local leaders echoed a lot of pleas to Houston Police Department and our mayor, John Whitmire, to call a local city-led criminal investigation into what happened on our streets.

But during City Council today, Mayor John Whitmire said that it's outside of the city's hands since HPD, Houston Police Department, was not involved in this altercation.

And a local council member said it would be very difficult for local law enforcement to conduct its own investigation since it only involved federal agents.

But there is pressure from congressional representatives down to local city council members, some of them, to have their own criminal investigation.

GEOFF BENNETT: How is this resonating in Houston?

We saw protests in Minneapolis over federal immigration efforts there, immigration enforcement, rather.

Is there a sense that this incident could spark protests in Houston?

COLLEEN DEGUZMAN: From what I know right now is, the city is in the heartache stage.

We're having a vigil tonight.

And a lot of people are grieving with the family for the loss of the dad and the detention of the three other men who were in the same vehicle with him.

From what we know, one of them was his brother, Ronaldo's uncle.

And so I'm unsure if this is going to spark protests, because the -- what I'm sensing from my reporting here in Texas so far is that a lot of people are in hiding.

And so that's really leading people to be nervous about going out in public, to be speaking out against the administration, especially here in Texas, where Governor Greg Abbott is supportive of President Trump's agenda to carry out the largest mass deportation operation in the country's history.

And so I think it's going to be very different here in Texas, and especially here in Houston, which is one of the most diverse cities in the nation, especially where this happened, in Houston's East End, which is a heavily Latino neighborhood.

GEOFF BENNETT: Colleen DeGuzman of The Texas Tribune speaking with us from Houston.

Thank you, Colleen.

COLLEEN DEGUZMAN: Thank you for having me.
