Jury Watches Death By Mercedes Video

The trial of Clara Harris, 44, for the murder of her husband with a Mercedes Benz, took a dramatic turn as the jury was left with the shocking image of the hulking vehicle in the parking lot as it repeatedly ran over the body of the victim.

"The evidence is going to show you that she intentionally hit him and didn't stop. She did it again and again and again," prosecutor Mia Magness told the jury.

And the court indeed saw the detail of the vehicle as it circled the lot again and again.

As CBS' Elizabeth Sanchez reports, a tearful Clara Harris watched with jurors the tape showing her driving erratically in a hotel parking lot after confronting David Harris and his mistress. The amateur photographer is a former employee of Blue Moon Investigations, the firm hired by the defendant to follow her husband.

Harris is accused of killing her husband David Harris July 24, the same day he had promised her he would end his affair, defense attorney George Parnham said.

Instead, based on information from a private investigator she had hired to follow her husband, Clara Harris found him with another woman at the same hotel where the couple had married on Valentine's Day a decade earlier.

Minutes before he was run over by a car in a hotel parking lot, David Harris watched but did not intervene as his wife threw punches and ripped the blouse of his alleged mistress, a witness testified.

"While Clara Harris was attacking Bridges, David Harris was standing off to the side," hotel clerk Paul Garrett Clark testified Thursday. "He never intervened."

Clark said he attempted to break up the fight between the two women when he saw Clara Harris hitting Bridges with a closed fist.

Prosecutors allege Clara Harris was angry her 44-year-old husband was having an affair with his former office worker. They allege after Clara Harris had a physical confrontation with the woman in the hotel's lobby, the spurned wife got into her Mercedes-Benz and ran her husband down.

Employee Evangelos Smiros told jurors that as Clara Harris was escorted from the hotel, he heard David Harris yell toward her: "It's over! It's over! It's over!"

Clara Harris then got into her silver sedan with her 16-year-old stepdaughter, Lindsey, Smiros said. Meanwhile, David Harris followed behind Bridges as she was escorted to her Lincoln Navigator.

After backing out of her parking space at the front of the hotel, Clara Harris hit the gas pedal and sped toward the back of the hotel, Smiros said. Bridges' vehicle was parked in an employee parking lot at the back of the building. Clara Harris sped into an open spot next to the Navigator, striking her husband and shearing off the vehicle's driver side door, Clark said.

"It's a sight I'll probably never forget for the rest of my life," Smiros said outside the courtroom.

When the Mercedes stopped, hotel employee Blake Doran said Clara Harris apologized to her husband and told him how much she loved him.

If convicted, she faces up to life in prison. If jurors determine she acted under the legal definition of sudden passion, they could consider a lighter sentence of two to 20 years in prison.

After testimony ended Thursday, Magness asked state District Judge Carol Davies to order that Clara Harris and David Harris' parents not contact Lindsey Harris. The prosecutor said the 17-year-old was "feeling pressured" by a phone call from Clara Harris last week and repeated calls from her grandparents, David and Mildred Harris.
