Michael Gargiulo, the California man known as the “Hollyknown Ripper,” was found guilty Thursday of murdering two women and trying to kill another.

A Los Angeles jury convicted Gargiulo, 43, for the 2001 slaying of Ashley Ellerin,22, in her Hollywood home and killing Maria Bruno, 32, in her El Monte home in 2005. Gargiulo was also convicted of trying to kill Michelle Murphy, who fought Gargiulo off and caused him to leave behind blood which led to his capture, according to KTLA.

The news outlet reported that the jury deliberated for three days before handing down the guilty verdicts.

In addition to Murphy, droves of witnesses testified during the monthslong trial. Among those who took the stand was Ashton Kutcher, who was Ellerin’s acquaintance and had a date planned with her on the night she was killed.

Kutcher had invited Ellerin to an afterparty for the Grammy’s and became concerned when she didn’t show up. The actor testified that he went to Ellerin’s home at around 10:45 p.m. and peeked through a side window. He recounted seeing what he thought was spilled wine before leaving, according to TMZ.

Ellerin was found dead in her home the following morning with 47 stab wounds.

The Los Angeles Times reported that Gargiulo first met Ellerin when he offered to help her fix a flat tire. After offering to help repair her heater, Gargiulo began coming to Ellerin’s apartment unannounced. It reportedly got to the point where he would park in front of her home and sit there for hours on end.

Gargiulo’s first victim is believed to be Tricia Pacaccio, 18, who was fatally stabbed in Illinois in 1993, when he was 17. Prosecutors said Gargiulo’s DNA, which was recovered from Murphy’s bedspread and sheet, was later matched to DNA found underneath Pacaccio’s fingernails, according to People.

Santa Monica police arrested Gargiulo for Murphy’s attempted murder in June 2008, before he was charged with Ellerin and Bruno’s slayings. He was charged with Pacaccio’s murder in 2011.

The sentencing phase of the trial is expected to begin on Tuesday.
