HOUSTON — Federal prosecutors confirmed Thursday that laboratory tests found the white, crystal-like material recovered from the work van of Lorenzo Salgado Araujo, who was fatally shot by U.S. Immigration and Customs Enforcement officers on July 7, did not test positive for methamphetamine.
Evidence testing and immediate reaction
U.S. Attorney Aaron Reitz provided the update to The Texas Tribune, saying the results were negative for meth. The specific composition of the substance was not disclosed by prosecutors. Family attorneys have described the material as a homemade electrolyte mixture Salgado Araujo and his construction crew used to stay hydrated in Houston’s summer heat.
"The tests were negative for meth," U.S. Attorney Aaron Reitz said in a statement to The Texas Tribune.
The denial of methamphetamine in the vehicle comes as the case remains a focal point in debates over immigration enforcement practices and the use of force by federal agents. Salgado Araujo, 52, a Mexican national who had lived in the United States for about 35 years, was killed after officers in unmarked vehicles chased his white work van and fired through the window while he was driving colleagues to a job site, according to accounts of the incident.
Broader context and oversight demands
The shooting is among at least 10 deaths linked to immigration enforcement operations since the start of what the source describes as President Donald Trump’s mass deportation campaign. The incident has prompted protests in Houston and demands for an independent investigation into the use of force by ICE officers.
Advocates and congressional members have called for transparency in the investigation and clarification on what led officers to stop and ultimately shoot Salgado Araujo. His family and their attorney maintain he had no criminal history and operated a homebuilding business.
- Date of shooting: July 7

Local leaders and civil rights groups have seized on the case to question both the tactics used in immigration enforcement and the accountability mechanisms that apply to federal agents. The shooting has also drawn attention on Capitol Hill; U.S. Rep. Sylvia Garcia, D-Texas, and other lawmakers have participated in oversight discussions over the death.
Officials have not released a full timeline of the ICE operation that led to the chase and shooting, nor have they publicly detailed whether officers identified themselves or the specific grounds for initiating the stop. Those unresolved aspects are central to calls for an independent review.
The family’s description of Salgado Araujo as a longtime resident who ran a homebuilding business and had no prior legal troubles has amplified public scrutiny. The contrast between that depiction and the presence of a crystal-like substance in the vehicle — now shown not to be methamphetamine — has complicated narratives around the circumstances of the shooting.
As investigations continue, the disclosure of the test results is likely to sustain pressure on federal authorities to provide more complete information about the operation and to clarify procedural safeguards for enforcement actions carried out by unmarked units. The case may also shape broader conversations about oversight of federal immigration agents and the standards governing the use of lethal force.
With protests having taken place in Houston, community leaders and elected officials are expected to continue pushing for transparency and, in some quarters, for a third-party investigation to assess the events that led to Salgado Araujo’s death.
