TRAVIS COUNTY, Texas — Bob Hilliard, founder of Hilliard Law Center in Corpus Christi, announced last Thursday that his firm has filed a lawsuit against Tesla, Inc., on behalf of Lillian Brady, an employee at Gigafactory Texas.

The suit stems from an alleged December 2025 assault by Ndiaga Diagne, the Tesla employee now accused of killing three people and injuring 17 others in a mass shooting in downtown Austin on March 2, 2026.

Filed in Travis County state district court, the lawsuit claims Tesla failed to provide a safe workplace, neglected to check employee backgrounds, and did not adequately monitor company areas or sanctioned activities. According to the suit, these failures created an unreasonably dangerous environment for Brady.

Brady alleges Diagne attacked her during a company-sanctioned prayer break, and that Tesla did not disclose his identity to her afterward. She only learned who her assailant was after media reports following the Austin shooting.

Hilliard said additional evidence suggests Diagne may have shown violent tendencies before the December incident. “If Tesla had acted on warning signs, Ms. Brady’s assault — and potentially the tragic events that followed — may have been prevented,” Hilliard said. “Every worker deserves a safe workplace. Companies the size of Tesla must be held accountable when they ignore warning signs.”

The case is ongoing in Travis County. Hilliard Law is representing Brady and her family as they seek justice and answers from Tesla.
