Minnesota officials say they can't access evidence after fatal ICE shooting and FBI won't work jointly on investigation

Minnesota's investigations agency said Thursday that the U.S. attorney's office has prevented it from taking part in the investigation into an Immigration and Customs Enforcement officer's fatal shooting of Minneapolis woman Renee Good, a 37-year-old mother of three.

"The investigation would now be led solely by the FBI, and the BCA would no longer have access to the case materials, scene evidence or investigative interviews necessary to complete a thorough and independent investigation," Minnesota Bureau of Criminal Apprehension Superintendent Drew Evans said in a statement.

It had been decided that the Bureau of Criminal Apprehension would investigate Good's shooting death along with the FBI, but that later was changed by the U.S. Attorney's office, according to Evans.

The BCA "has reluctantly withdrawn from the investigation," Evans wrote.

The announcement came as protestors and law enforcement clashed Thursday morning outside a Minneapolis immigration court, with the governor urging restraint and schools canceling classes as a precaution. Asked about the development, Homeland Security Secretary Kristi Noem said Thursday that Minnesota authorities "don't have any jurisdiction in this investigation."

Governor objects to feds freezing state out of investigation

Minnesota Gov. Tim Walz criticized the Trump administration Thursday for freezing Minnesota out of the investigation.

"It feels very, very difficult that we will get a fair outcome," Walz said at a briefing for reporters. "And I say that only because people in positions of power have already passed judgment, from the president to the vice president to Kristi Noem, have stood and told you things that are verifiably false, verifiably inaccurate."

Public Safety Commissioner Bob Jacobson said he'd welcome the chance to get his agents back involved in the search for answers.

"For us to be able to do that, it would be extremely difficult, if not impossible, without cooperation from the federal government," Jacobson said.

Hennepin County Attorney Mary Moriarty said her office is "exploring all options to ensure a state level investigation can continue" and that they're "speaking to our local partners on paths forward."

Minneapolis Mayor Jacob Frey said Thursday he's dismayed that the FBI and Justice Department have blocked the state out of the investigation.

"Is it problematic? Absolutely. Am I concerned about this development? Of course, I am," Frey said in an interview with The Associated Press.

"We want to make sure that there is a check on this administration to ensure that this investigation is done for justice, not for the sake of a cover up."
