DENVER (AP) — Federal prosecutors have charged a woman in a string of vandalism against a Colorado Tesla dealership, including throwing Molotov cocktails at vehicles and spray painting “Nazi cars” on the building along with a message that appeared directed at company co-founder Elon Musk.

Lucy Grace Nelson appeared in federal court in Denver briefly Thursday after being arrested on a federal charge of malicious destruction of property. Her ankles and wrists were shackled and she wore a purple tie-dye shirt and red-and-black checked pants, as she sat in the jury box with other defendants waiting for their cases to be called.

Nelson rocked back and forth slightly as Magistrate Judge N. Reid Neureiter informed of her rights and Nelson’s mother watched from the front row of the gallery.

When Neureiter questioned lawyers about why federal charges were brought, Nelson began to speak but her attorney, public defender Jennifer Beck, rushed across the room to stop her. Cassie Wiemken of the U.S. Attorney’s Office said the federal government had a compelling interest to prosecute the case because of the danger posed by the “incendiary devices” allegedly used.

After Neureiter noted that Nelson did not report any income or expenses in her application for an attorney, Beck told him that she receives support from her family.

Nelson’s mother and attorney declined to comment after the hearing.

Nelson’s sister, Jennifer McCown, said that her sister loves her family and has been recently volunteering to feed the homeless.

“She’s a loving, intelligent person who wouldn’t hurt another person for the world,” McCown said in a text. She did not comment on the allegations Nelson is facing.

Nelson was arrested Monday on separate state charges after police said she returned to the dealership in Loveland, Colorado with “additional incendiary devices” and materials used in vandalism. However, it wasn’t clear whether state prosecutors have filed formal charges against her. Police said Wednesday that they expected federal charges to be filed.

The case comes amid rising concerns voiced by Democrats and some Republicans about Musk’s influence over the administration of President Donald Trump and follows recent protests at Tesla storerooms elsewhere in the U.S.

Trump and cost-costing chief Elon Musk’s Department of Government Efficiency, or DOGE, have been moving to slash the size of the federal government through large-scale layoffs, contract cancellations and other moves.

According to the federal criminal charges filed against Nelson, she is suspected of starting fires by igniting Molotov cocktails crafted from empty liquor bottles near vehicles that apparently did not cause much damage.

Photos included in the filing showed a small fire on the ground near vehicles. The dealership estimated that several incidents of vandalism over the course of about a month caused between $5,000 and $20,000 in damages, with an estimated $5,000 in damage to the vehicles.

Loveland police spokesperson Chris Padgett said police were investigating the possibility of someone else being involved.

In one of the incidents, someone spray painted an obscenity believed to be directed at Musk before being chased away by a security guard, according to a Loveland police affidavit.

Police said that at the time of Nelson’s arrest, they saw in her car cans of spray paint, gasoline, bottles and various cloth pieces that could be soaked with an accelerant.
