CAPT Robert Clark, Commanding Officer, Naval Station Norfolk said a suspect approached the USS Mahan’s Quarterdeck at 11:20 pm Monday night and was confronted by ship security personnel. “A struggle ensued and the suspect was able to disarm the Petty Officer of the Watch. The suspect then used the weapon to fatally shoot our Sailor responding to render assistance. Naval security forces then killed the suspect. The suspect did not have his own weapon,” said Clark. The Naval Criminal Investigative Service (NCIS) is investigating possible motives.
