Ashton Kutcher, Ashley Ellerin

Ashton Kutcheris scheduled to testify Wednesday in the trial of suspected serial killerMichael Gargiulo,who faces two counts of murder in connection with the deaths of two women — including Kutcher’s friend Ashley Ellerin.

Ellerin, 22, had planned to attend a post-Grammy party with Kutcher on the evening of Feb. 21, 2001. Instead, prosecutors allege Gargiulo snuck into her Hollywood home and stabbed her 47 times while she was getting ready for her outing with the actor.

“We believe she had just exited the shower and was getting ready to go out with Mr. Kutcher when she was attacked from behind,” Los Angeles County Deputy District Attorney Dan Akemon said in a Los Angeles courtroom during the trial’s opening statements.

The 41-year-old star ofNetflix’sThe Ranch, who is now married to actressMila Kunis, is one of more than 100 witnesses who have or are scheduled to testify in the murder trial of 43-year-old Gargiulo, who prosecutors have described as a “serial, psychosexual thrill killer” whostalked and then viciously stabbedhis unsuspecting victims — all young women who lived near him.

Gargiulo was a 24-year-old air conditioning repairman and former bouncer at the Rainbow Bar & Grill when he first met Ellerin, a student at L.A.’s Fashion Institute of Design and Merchandising, outside her home in the fall of 2000, asking her if she needed help fixing a flat tire.

Ellerin’s friends later told police that Gargiulo, who lived less than a block from her, would show up to her house uninvited. Another friend said he saw Gargiulo parked outside her bungalow at odd hours, surveilling her home.

On the evening of Feb. 21, 2001, Ellerin spoke to Kutcher at 8:24 p.m. to confirm their plans.

Kutcher called Ellerin again at 10:15 p.m. but there was no answer.

“[Kutcher] believed at that point he had been stood up,” Akemon said.

Kutcher later told police that before he left, he peered through a front window and saw what he believed were red wine stains on the floor. Prosecutors allege that the stains were blood.

“We believe now the evidence will show that was actually blood, and Ashley had already been murdered,” Akemon said.

Ellerin’s roommate found her body the following morning.

Akemon said Kutcher’s testimony is part of the “chronology of this case” that shows “there was a … very narrow window of opportunity for someone to get into the house and murder Ashley, and whoever that person was must have been watching.”

Gargiulo is also charged with the 2005 murder of Maria Bruno, 32, and the attempted murder of Michelle Murphy, who wasviciously stabbedin her Santa Monica home in 2008.
