A west suburban Addison woman accused of violently shaking a 3-month-old baby pleaded not guilty nearly 15 years after she fled to avoid prosecution.

Rosa Tellez, 43, was arrested last week in DuPage County. Police had stopped her for a traffic violation when they found she was wanted on a 1995 warrant.

Tellez had been babysitting the infant, who was found with brain injuries.

Investigators say Tellez left a note behind saying she was leaving the country for Mexico. The baby involved survived and is now 15 years old and living out of state.
