AUSTIN, Texas — A former Tesla employee’s recent lawsuit against the company reveals new information about the gunman in last week’s deadly shooting at an Austin bar.
According to the lawsuit, Ndiaga Diagne assaulted plaintiff Lillian Mendoza Brady on Dec. 4, 2025, while Diagne took an employee-sanctioned prayer break in a common area at the company’s headquarters outside of Austin, where they both worked.
The shooting at Buford’s early Sunday left four people dead, including the gunman, and over a dozen injured. Police identified the gunman as Diagne.
Brady is suing the company for negligence and is seeking monetary relief of over $1 million. Elon Musk’s Tesla, Inc. is named as the defendant. The company has faced scrutiny in recent years over Musk’s political leanings, as well as vehicle safety concerns.
The lawsuit alleges that Tesla, Inc. had knowledge of Diagne’s “volatile temperament and propensity for aggression,” but “took no steps to monitor the common areas or supervise sanctioned activities in those spaces.”
It adds that the company “committed acts of omission and commission” and that it “owed a duty to supervise its employees to prevent foreseeable harm to others.”
“By allowing unsupervised prayer breaks in shared common areas involving an employee with known aggressive tendencies Defendant breached its duty of care. This negligence was a proximate cause of the physical injuries and damages sustained by the Plaintiff,” the lawsuit says.
Brady is seeking recovery for damages including past and future physical pain and mental anguish, lost wages, medical expenses and more.
“The conduct, failures, acts, and omissions of Defendant described above, were more than momentary thoughtlessness, inadvertence, or error of judgment and were of such a character as to constitute gross negligence and therefore subject Defendant to punitive damages,” the lawsuit says.
