Police in Louisville are mourning the loss of 32-year old Deidre Mengedoht… a detective with the Louisville Metropolitan Police Department who died Monday in an accident on I-64. Investigators say the officer was in her patrol cruiser after checking on a truck that had caught fire and pulled over, when her cruiser was hit by a semi truck. The impact forced her cruiser into the stopped car, trapping her inside as her vehicle caught on fire. She died at the scene. The semi driver was arrested and charged with DUI and murder.
