I wonder what conclusion the FBI's investigation will come to because it sure doesn't look good for ICE to me. Best case, those two agents get sentenced to life for murder but the damage is done and a life taken. If the officer fired two shots and she died at the scene then it seems reasonable to me the bullets didn't go through the windshield and, instead, went through her rolled down window while she was turning away from the officer. If that's the case then I'm predicting riots everywhere over the next couple weeks.

Given that this administration appointed the head of the FBI due to his loyalty to Trump, the most likely reason they took over the investigation is to shield ICE from any accountability.
The US FBI now seems to act much as the National Enquirer does, as a "catch and kill" tool.
In the case of the Enquirer, this was through buying exclusive rights to inconvenient stories and refusing to publish them. In the case of the FBI, it's by claiming exclusive jurisdiction over incidents and quashing or impeding independent investigation.
