A 21-year-old woman accused of playing a role in events that led up to the March slayings of two Coronado High School students will serve three years of supervised probation. Initially charged with five counts, including kidnapping and assault, Breeana Eloise Dahlberg pleaded guilty in July to false imprisonment. Although prosecutors say her actions played a role in the deaths of Natalie Partida, 16, and Derek Greer, 15, her crimes related to a third party, not the slain teens, her attorney said after her sentencing hearing Tuesday. "The person involved in this case is alive and well," said attorney Jennifer Stock. Dahlberg's sentence was imposed by 4th Judicial District Judge Larry E.
