A lawyer for the family of Lorenzo Salgudo Araujo is explaining the "crystal-like substance" that was seen in the van targeted in last week's ICE-involved shooting in Houston.

The backstory: The FBI requested to search the white van that was being driven by Araujo when he was shot and killed by an ICE agent.

According to an affidavit filed in federal district court Tuesday, investigators said they saw several plastic bags with a "white crystal-like substance" in plain view from the outside of the van.
