( CNN ) -- There will be no criminal charges filed in the death of a Green Beret who was electrocuted in his quarters in Iraq last year , the Department of Defense said Friday . Staff Sgt . Ryan Maseth , a 24-year-old Green Beret , died in a shower at his base in Iraq in January 2008 . The Army 's 11-month investigation `` concluded that there is insufficient evidence to prove or disprove that any one person , persons or entity was criminally culpable '' in the death of Staff Sgt . Ryan Maseth , the Department of Defense said in a written statement . Maseth , a 24-year-old decorated Green Beret from Pittsburgh , Pennsylvania , was electrocuted in a shower in his Baghdad quarters -- a former palace of deposed Iraqi leader Saddam Hussein -- in January 2008 . `` The investigation revealed that there were numerous entities , individuals , both contractors and government employees , who breached their respective duties of care ; however , none of those breaches , in and of themselves , were the proximate cause of his death , '' the Army said . A report released last month from the Pentagon 's inspector general found that Maseth 's death stemmed from failures both by the U.S. military and by military contractor KBR . The company did not properly ground and inspect electrical equipment , the inspector general 's report found , while Maseth 's commanders failed to ensure that renovations to the building where he was based had been properly done . The Army did not set electrical standards for jobs or contractors . KBR has said the palace was not properly grounded by contractors when it was built . The Pentagon report concluded that KBR failed to ground a water pump at the building , and the company did not report improperly grounded equipment during routine maintenance . Maseth 's family is suing the company . After the Pentagon inspector general 's report Sens . Byron Dorgan of North Dakota and Bob Casey of Pennsylvania , both Democrats , called on the Pentagon last month to take back more than $ 83 million in bonuses paid to KBR . Casey said the Pentagon should fine KBR : `` Make it hurt and make it count . '' The Department of Defense said there were 18 reported deaths caused by electrocution in Iraq since the war began and that a task force designed to assess fire and electrical safety issues in Iraq was created `` after a series of electrical accidents and incidents . '' The task force has inspected more than 67,000 of the approximately 90,000 pieces of equipment and facilities in Iraq . Almost 14,000 deficiencies have been corrected , the department said .
