A DuPage County judge raised bail Wednesday for a former Villa Park woman accused of murdering her girlfriend last year at their shared home.

DuPage Circuit Judge John Kinsella ruled that Nicole Abusharif, 27, violated the conditions of her release by going next door to her brother’s apartment on the 5700 block of Circle Drive in Oak Lawn. He raised her bail by $100,000. She will remain in DuPage County Jail unless her family posts $10,000 bond.

Prosecutors sought to have her bond revoked in order to keep her in custody at the jail while she awaits a trial.

Abusharif was released April 26, 2007, after her family posted $100,000 bond, 10 percent of her $1 million bail. She was placed under home confinement and is only allowed to leave to go to court or meet with her attorney. She is attached to an electronic monitoring device.

Abusharif is accused of murdering Rebecca Klein at their shared home in Villa Park on March 15, 2007, and attempting to conceal the murder. Klein, 32, was suffocated with a plastic garbage bag and stuffed in the trunk of her 1966 Ford Mustang, which was left in the garage of the home at 250 N. Harvard Ave., police said.

After receiving a tip from a neighbor last month, Villa Park police Detective Daniel McCann went to Abusharif’s apartment complex at about 3:30 p.m. April 25 and observed her leaving her brother’s building, entering her own and then returning to her brother’s, McCann testified Wednesday  at a bond hearing.

The neighbor, who prosecutors would not identify in court due to the nature of the charges against Abusharif, told authorities she had seen Abusharif outside her apartment on numerous occasions, going back and forth to her brother’s apartment and playing with neighborhood children.

Abusharif’s attorney, Dennis Sopata, said his client was not clear on the conditions of her release because investigators with the DuPage County state’s attorney’s office told her she could leave her apartment to do laundry in her building or go to her mailbox.

Investigator Ray Bradford testified that when he was setting up Abusharif’s monitor after she was released, he told her and her father that the device has a range of about 100 feet. He told her she might be able to get the mail or do laundry without setting off the device, but made it clear she was not to leave the apartment for other reasons, he said.

In finding that she violated her bond, Kinsella said Abusharif should have understood the conditions.

“She was told to stay in her apartment, that the only exceptions were to go to court, to see her attorney or for emergency medical situations,” Kinsella said.

If Abusharif’s family is able to post bond, Kinsella said he will issue an order clarifying that she is to stay within her own apartment and the common areas of her apartment building.

Assistant state’s attorney Joe Ruggiero said Abusharif committed murder in a “cold, calculated, vicious way” and should remain in custody.

“This defendant should never have been allowed to leave jail,” Ruggiero said.
