A man has been charged for the murder of Ashton Kutcher's ex-girlfriend Ashley Ellerin - seven years after her death.

Michael Gargiulo, 32 - who has been behind bars since July after being arrested for an April knife attack - was formally charged with the murder of Ellerin and another woman on Thursday. The 22-year-old's body was found in her Hollywood Hills home in February 2001.

Kutcher told police at the time of the incident that he had gone to pick up the fashion student/model from her home to attend a post-Grammy Awards party, but she failed to answer the door. He said he left the property after checking a back window and spotting what he thought to be red wine stains on the carpet. Ellerin was found dead the following day by a friend.

Santa Monica police Lieutenant Darrell Lowe revealed last week that DNA evidence collected from a crime scene earlier this year indicated that Gargiulo was responsible for the stabbings of women in Chicago, Illinois, Los Angeles, and Monterey Park, California. The Illinois murder dates back to 1993. Garguilo has been held on $1.1 million bail for the last two months on attempted murder and burglary charges. But Garguilo insists he is not guilty.

His attorneys Elana Goldstein and David Murphy tell website TMZ.com, "Our client vehemently denies all allegations against him and any involvement in any of these murders."

Kutcher, who is now married to Demi Moore, has so far refused to comment on the new developments.
