The "crystal-like substance" the FBI found inside the van of Lorenzo Salgado Araujo - the 52-year-old who was fatally shot by an ICE agent in Houston earlier this month - was not an illicit drug, according to U.S. Rep. Sylvia Garcia, D-Houston, the Harris County District Attorney's Office and a lawyer representing Salgado Araujo's brother.

"We can now confirm that the substance found in Lorenzo Salgado's van was not a narcotic or any other illicit substance," Garcia said on social media, without revealing the source of the information.

"As his family has said all along, this was an electrolyte powder to stay hydrated working outside in the hot Texas summer. The attempt to cast a shadow over Lorenzo Salgado's name has failed." District Attorney Sean Teare's Office said in a statement that it was not commenting on the test results - which have not been publicly released by the FBI - but that it also has "been notified that lab testing of the substance found in Lorenzo Salgado Araujo's van was negative for narcotics/ illicit drugs." Ruby Powers, a Houston immigration attorney who is representing Victor Hugo Salgado Araujo, Lorenzo's brother, said the Texas Department of Public Safety, which tested the substance, told Salgado Araujo's family the preliminary test results show it wasn't an illegal drug.
