A Santa Clarita woman who allegedly stole a car and caused a fatal wrong-way five-vehicle collision on the 210 Freeway returned to court Wednesday.

In Fall 2018, the defense declared doubt as to Nicole Thibault’s mental ability to assist in her own defense, causing the case to be suspended until a mental evaluation could be done, according to officials from the Los Angeles County District Attorney’s Office.

On Oct. 22, 2018, Thibault was found mentally competent to stand trial and criminal proceedings were reinstated, according to the D.A.’s office.

In May 2018, Thibault pleaded not guilty to one count of murder, one count of grand theft, six counts of attempted murder and six counts of assault with a deadly weapon, according to the D.A.’s  Office.

Prosecutors said that on Jan. 22, 2018, Thibault stole a parked truck in San Bernardino. She then allegedly drove through several red lights at unsafe speeds before entering the 210 Freeway, prosecutors added.

In the backseat of the stolen vehicle was a two-year-old child, according to CHP officials.

About a mile from where the car was stolen, the woman pulled over, carried the boy out of the car and left him on a sidewalk near Temple and H streets, where the child was found safe, according to authorities.

Thibault then allegedly entered the 210 Freeway going the wrong direction, traveling west in the eastbound lanes for over 20 miles. She then collided head-on with several cars, according to prosecutors.

Responding CHP units attempted to get into position to stop the vehicle; however, a pursuit was never initiated, officials said.

“As the Ford F-150 continued traveling wrong-way within the center median of SR-210, for unknown reasons it veered into oncoming traffic and collided with four vehicles,” according to CHP officials. “It is unclear where the Ford F-150 entered the freeway and why the suspect was driving wrong-way.”

Daniel Castillo, 69, died from injuries sustained in the crash. Six other victims also suffered injuries, according to prosecutors.

If convicted as charged, Thibault faces a maximum possible sentence of 57 years to life in prison.

Thibault is currently being held at the Century Regional Detention Facility in Lynwood, with bail set at $8 million.

She is scheduled to return to the Pomona Branch Courthouse on Aug. 21 for a preliminary hearing.
