Actor Ashton Kutcher told a Los Angeles jury on Wednesday that he was "freaking out" after learning that a young woman was found dead in Hollywood the day after he called her home for a date.
The two former and a half men's star witnessed as a witness at the trial of a man called Hollywood Ripper, accused of the murder of the young woman and two others.
Kutcher said he arrived at the Hollywood bungalow of fashion design student Ashley Ellerin on the night of February 22, 2001
But when he came there two hours after the call, Kutcher said he found the lights on and the door locked. Peering through the window he saw "what I thought was a red wine spilled on the carpet."
"I didn't really think of it," Kutcher said, adding that he "figured I turned up" by showing late, and he assumed that Ellerin had gone out with a friend, City News reported.
Ellerin, 22, was found dead in her home the next morning by a roommate. She had been piled 47 times, prosecutors said.
Kutcher, now 41, said when he learned what had happened to Ellerin, he spoke to the police and was "freaking out" because he knew his fingerprints would be at the front door of her home.
Michael Gargiulo is in Los Angeles's supremacy for the killing of Ellerin and two other women and attempting to murder another.
Gargiulo, 43, was arrested in 2008. He has not claimed guilty.
