Gargiulo, 43, has pleaded not guilty in court to two counts of murder and an attempted-murder charge that involved attacks in the Los Angeles area between the years of 2001 and 2008, one of which included the death of Kutcher’s former girlfriend, 22-year-old Ashley Ellerin.

Recently, the case had stirred significant attention when discovered that actor Ashton Kutcher will be one of the 250 witnesses present to testify in court.

Gargiulo is accused of murdering Ashley Ellerin on the night of February 21, 2001, court documents claimed. That night, according to prosecutors, Ellerin had missed a date with Kutcher, who invited her to an after-party for the Grammy Awards. When she didn’t arrive, Kutcher went to her home and glanced through one of her windows.

“Mr. Kutcher looked in the window and saw what he thought was spilled wine on the floor,” Akemon told the jury, according to KABC. “We believe now the evidence will show that was actually blood, and Ashley had already been murdered.” She was stabbed 47 times.

Gargiulo is facing a maximum sentence of life without the possibility of parole, and prosecutors are determined to prosecute him.
