A memorial for Lorenzo Salgado Araujo, who was fatally shot by an immigration officer in Houston.

Credit: Texas Tribune / Jon Shapley Harris County District Attorney Sean Teare said Friday that federal officials have not provided his office any information about the fatal shooting last month of Lorenzo Salgado Araujo by immigration officers in Houston, so he plans to take the evidence his office has collected so far to a grand jury in the "next few weeks," in part to compel the release of more details.

Teare said his office also may file a federal lawsuit to force the Department of Homeland Security, which oversees U.S. Immigration and Customs Enforcement, to provide more information.
