Military contractor KBR Inc. was responsible for the negligent homicide of a soldier killed by electrocution while serving in Iraq, an Army investigation has determined. Staff Sgt. Ryan Maseth died of cardiac arrest in 2008 when he was electrocuted while taking a shower in his Baghdad barracks. According to the Army investigation, KBR failed to provide qualified personnel to work on electrical wiring in the barracks. A wrongful death lawsuit in connection with Maseth’s death was filed last year.
