"In a dramatic and public incident, all captured on surveillance video, Brenda White, 36, allegedly chased her husband, Jon White, through a parking garage in her Ford Explorer, plowed into a Salt Lake County office building and then crashed the vehicle into him."
"Brenda was arrested and charged with attempted murder. She was later released on $500,000 bail.
Taking the witness stand Thursday in her own defense, Brenda White told the court that she had taken a handful of Xanax before heading to the Woodland Towers office building, and had heard her husband on his phone in the parking garage telling someone else that he loved her, The Salt Lake Tribune reported."
"In a Utah courtroom this week, Brenda White's attorneys argued that she was suffering "extreme emotional distress" in the moments that she crashed through the building. They say she was suffering from panic attacks from problems with her husband, and lost control when she took too much Xanax."
Voluntary intoxication is often not a defense to criminal acts. Additionally, driving while under the influence of a drug such as Xanax constitutes driving under the influence in many states.
