Mayor John Whitmire is expected to provide an update Friday afternoon on the investigation into the fatal shooting of Lorenzo Salgado Araujo by a U.S. Immigration and Customs Enforcement agent, days after the incident sparked calls for greater transparency from local leaders.

Whitmire will be joined at a 2:30 p.m. news conference at Houston City Hall by U.S. Rep. Sylvia Garcia, Houston Police Chief Noe Diaz and other local officials to discuss the latest developments in the July 7 shooting.

The briefing comes after the mayor announced Friday morning that, at his direction, Diaz has sent letters to the U.S. Department of Homeland Security and the FBI, offering the Houston Police Department's assistance with the ongoing investigation.
