MARYSVILLE, Wash. (Metro) -- A Marysville police officer whose daughter was accidentally shot to death by a sibling faces a charge of second-degree manslaughter. Snohomish County prosecutors say Officer Derek Carlile created a hazardous situation by leaving his loaded, unsecured handgun within reach of four children. Seven-year-old Jenna Carlile died on March 10th after her three-year-old brother picked up the .38-caliber revolver and fired it in the family's van in Stanwood. Arraignment for Derek Carlile is scheduled for June 5th. Copyright © 2012 Metro Networks Inc.
