Nekiylo Dawayne Graves

Deadly force

Nekiylo Dawayne Graves drove up to the main security gate at the Nevada nuclear test site in Mercury at about 5:20 p.m. but didn't stop, police said. When Graves drove past the gate, security officers called for help from the Nye County Sheriff's Office substation at the test site. Deputy John Kakavulias caught up with the security officers chasing Graves, who stopped the car about 8 miles from the gate along Mercury Highway. Graves got out of the car and approached a security officer and Kakavulias with an unspecified object in his hand. He was shot and killed.
