A federal judge in Chicago will allow the release of evidence, including body camera video footage and text messages, from the October shooting of Marimar Martinez, a 30-year-old teacher’s assistant, by a Border Patrol agent in Chicago.

On Friday, Judge Georgia N. Alexakis of the Federal District Court for the Northern District of Illinois said she would allow the release of text messages from Charles Exum, the agent who shot Ms. Martinez, and video of the incident, as soon as the materials were redacted to obscure the identities of other parties. That could happen as soon as Monday, Ms. Martinez’s attorney said.

The evidence was gathered as part of the now-defunct criminal case against Ms. Martinez and had been sealed by a judicial protective order.

In its filings, the government has argued that releasing the text messages “will serve only to further sully Agent Exum, his family and co-workers.”

Ms. Martinez’s attorney, Christopher V. Parente, responded that it would be “a fully deserved self-imposed sullying,” following a “campaign of lies” against Ms. Martinez by the Department of Homeland Security. After the hearing on Friday, he praised the judge’s ruling. “You can’t call a U.S. citizen with no criminal history who’s a Montessori schoolteacher a domestic terrorist,” he said.

Ruling from the bench, Judge Alexakis said Ms. Martinez had “demonstrated good cause to warrant the release of the text messages,” because they “will counter the government’s public narrative of her and her actions.”
