Aaron Reitz, the newly sworn US Attorney for the Southern District of Texas, is sharing new details on what led up to last week's fatal Houston shooting involving ICE officers.

What they're saying: In a statement, Reitz says the ICE officers were initially looking for "two Guatemalan men known to be driving a white van." The two men were "potentially subject to deportation" and have avoided being arrested in the past.

While looking for the suspects' van, ICE officers were told about a similar van in the area.
