OAKLAND — Noor Zahi Salman, the widow of the man who killed 49 people in an Orlando nightclub last summer, pleaded not guilty Wednesday to charges she helped her husband plan the massacre and hinder the criminal investigation.

Salman, 30, walked into the Oakland federal courtroom with her shoulders slumped and her head hanging down, wearing a red jumpsuit that indicates she may be in protective custody in Santa Rita Jail. She has been in custody without bail since FBI arrested her at her family’s Rodeo home early Monday morning, following a seven-month investigation.

A hearing on whether she should be released on bail, at which attorneys will give details of her alleged crimes, is scheduled for Feb. 1.

Salman faces life in prison, charged with aiding her husband in a terrorist attack and obstruction of justice. Prosecutors alleged the young mother knew her husband Omar Mateen was planning an attack. Her family and attorneys said she was in the dark to her abusive husband’s plans.

After the massacre, she and her 4-year-old son moved from Florida to Contra Costa County, where she was raised and attended John Swett High School in Crockett.

Salman is expected to be extradited back to Florida at some point. A Florida grand jury indicted her with regard to her involvement in the shootings at the Pulse nightclub in Orlando.

The two-count indictment alleges that Salman aided and abetted her husband from April to June 12, 2016, the day of the massacre. It alleged Salman provided “material support or resources” to the Islamic State, to which Mateen pledged allegiance during his attack.

Mateen, 29, was the only gunman at the Pulse nightclub, and he was killed after a three-hour siege in a shootout with police. Salman has said in an interview with The New York Times that her husband was abusive and led a secretive life, and she has denied any knowledge of his plans, despite reportedly once attending the Pulse nightclub with him.

Salman’s uncle Al Salman on Tuesday spoke at length with a large group of media, claiming his niece knew nothing of the attack and was a sweet, doting mother held captive by an abusive husband. Al Salman said Noor was “devastated” and surprised by the charges and the legal system would eventually free her and realize she had nothing to do with the crime.

Al Salman declined to address the media a second day, and on Tuesday was chased up and down the street outside the Oakland federal courthouse by some journalists after he refused to comment.
