A Sonoma State University student was sentenced Wednesday to five days in jail and nearly four months of home detention for running down and killing a 2-year-old girl in Rohnert Park while texting on her phone.

Kaitlyn Dunaway, 19, who pleaded no contest in September to misdemeanor vehicular manslaughter, could have faced up to a year in jail for the Dec. 1, 2010, crash that killed Calli Murray and injured her mother, Ling Murray.

But Judge Bradford DeMeo of Sonoma County Superior Court ordered Dunaway to surrender Dec. 27 to begin serving a five-day jail sentence. She must spend an additional 115 days in home detention while under electronic monitoring, he said.

She is free to leave her home for work, school and to perform 200 hours of community service by speaking to groups about the dangers of texting while driving. Calli's father, Jeff Murray, who had hoped for a longer jail sentence, and grandfather, Al Andres, will be notified about the speaking engagements so that they can appear with her to provide their perspective, prosecutors said.

Calli was holding her mother's hand as the two left Sunrise Park in Rohnert Park and started across Snyder Lane at Medical Center Drive. Dunaway was texting while driving her Honda and slammed into the two, killing the girl and badly injuring her mother.

A police investigation determined that Dunaway was not at fault in the crash, but prosecutors said they had filed charges against her because they believed she played a role in Calli's death.

District Attorney Jill Ravitch said Dunaway was texting, driving at a speed that was unsafe for the conditions and failed to yield to Calli and her mother - all illegal acts that do not amount to felonies.

Outside court, defense attorney Chris Andrian said his client was a "stellar, standup, strong, contributing member of society" and that the sentence would "give her a chance to stay on the right track with her life."
