IREDELL COUNTY, N.C. -- Charges were dropped Friday against an Iredell County teacher who was accused of stabbing her boyfriend to death, according to WBTV.
Dawn Bridget Kavanaugh was arrested on charges of fatally stabbing 43-year-old Ronald Ketchum at a home in Mooresville on Feb. 10.
Officials said Ketchum was killed with a kitchen knife in what they previously described as an apparent domestic situation. The two reportedly lived together.
Authorities said Ketchum was taken to Lake Norman Regional Medical Center and then transferred to Carolinas Medical Center where he was pronounced dead.
The charges against Kavanaugh were dropped nearly seven months after her arrest.
"At the conclusion of this supplemental investigation, the decision was made to dismiss the charge of first degree murder against the defendant, Dawn Kavanaugh," the court papers state.
The court papers said that the Conference of District Attorneys was contacted to handle the case due to a conflict with the District Attorney's Office in Iredell County.
Kavanaugh was reportedly the Middle School Teacher of the Year at Lakeshore Middle School in Mooresville for the 2011-12 academic year. She has taught sixth grade social studies at the school since 2010.
