State Sen. Carol Alvarado is raising new questions about an FBI search warrant that says investigators found multiple bags containing a "white crystal-like substance" they believe "is consistent with methamphetamine" inside Lorenzo Salgado Araujo's work van.

The details comes a little more than a week since the fatal shooting by ICE agent in Houston.

The warrant, filed July 14, is the latest public filing connected to the July 7 shooting in the Magnolia Park neighborhood.
