Prosecutors presented the evidence about Arias' road trip today in the seventh day of her murder trial, interviewing the Budget rental car franchise owner who rented her the car and playing interrogation tapes from the Mesa, Ariz., police department.
Arias, now 32, is accused of murdering Alexander, 30, by stabbing him 27 times, slashing his throat, and shooting him in what prosecutors said was a jealousy-fueled road trip to his home. She could face the death-penalty if convicted.
Arias denied her involvement in the killing throughout months of police interviews, saying she had never held a gun or used a knife to stab someone and refusing to admit she was in Mesa at the time of Alexander's death.
She later altered her story to admit she had visited Alexander, but said he was killed by two masked intruders, a man and a woman.
Arias finally admitted to killing her ex-boyfriend and claimed it was self defense, saying that he was abusive and controlling. Her attorneys have called Alexander a "sexual deviant."
The owner of the Budget rental car agency where Arias rented the car testified today that she specifically requested a car that was not "loud in color." When he offered her a red car, she asked for a "lighter color car," Raphael Colombo, the Budget owner, said.
She rented a white Ford Focus from Colombo in Redding, Calif., and said she would only be driving locally with it, and then proceeded to drive to Arizona. There, she had sex with Alexander, took nude photos of him, and then killed him, before driving to Utah to visit a new love interest and then back to California, according to testimony made during the prosecution's arguments.
"When she returned it, the car had a little bit more miles on it for being local," Colombo said, noting that the car had driven nearly 3,000 miles.
The car also had two large, conspicuous red stains on the front and back seats. All four floor mats were also missing from the vehicle.
Colombo said he cleaned the stains, on the front passenger seat and the middle back seat, which had the largest stain.
"It appeared to be Kool-aid," he testified.
Prosecutor Juan Martinez also questioned Michael Galleti, a police officer who pulled Arias over when she was driving the rental car through Utah. He stopped her car after noticing the license plates were upside down.
"I saw that the rear license plate on the car was mounted upside down," Galleti testified."(Arias was) pleasant, and, I think, surprised to learn that the license plate was improperly displayed."
In interrogation tapes played in the courtroom a month after Alexander's death, Arias can be heard telling Detective Esteban Flores, the lead investigator, that she hadn't gone to Mesa and asked whether he had checked red light cameras for her license plate.
"No. Not unless you ran the red light," Flores said.
Prosecutors have also admitted receipts and cell phone records into evidence showing that Arias was in Mesa at the time of the murder and lied about her whereabouts.
In previous days' testimony, the prosecution has submitted nude photos that Arias and Alexander took of each other on the day he died as well as photos of Alexander in the shower just moments before he was killed.
After leaving Alexander's home in Arizona, she drove to Utah where she had a date with a new love interest, according to testimony.
