Houston Police Department Chief J. Noe Diaz sent a letter to the director of the Texas Department of Public Safety requesting the Texas Rangers conduct their own investigation into the shooting of Lorenzo Salgado Araujo by an ICE agent.

"During the past week, Chief Diaz and Mayor Whitmire have spoken several times with state and local agencies to ensure a transparent and thorough investigation following the deadly ICE shooting. This afternoon, the mayor directed Chief Diaz to send the letter in response to the DPS letter to state lawmakers saying it needed a formal request. This step is intended to formalize the request and pledge full resources to ensure communication, accountability, and transparency throughout the process," a statement from a city spokesperson read.

In the letter, Diaz says the Houston Police Department "recognizes the seriousness of the matter and continues to support a thorough investigation." "Mayor Whitmire and I are asking the Texas Rangers to conduct their own investigation which will ensure it is independent and transparent. This has been done in previous cases," Diaz says in the letter.
