Chattanooga, TN - 5 murdered at 2 Sites: Armed Forces Career Center & Navy Operational Support Center - July 16, 2015

As the death toll in Thursday's massacre of Marine and Navy personnel by a radical Islamist in Chattanooga, Tenn., climbed to five Saturday, it was revealed that the jihadist once secured a job at a U.S. nuclear plant but was let go when he reportedly failed a drug test.

The Navy announced Saturday that Navy Petty Officer 2nd Class Randall Smith, 24, had died from his injuries. Smith was one of three people injured when Kuwaiti-born Muhammad Youssef Abdulazeez opened fire at two military recruitment centers, also killing four Marines. Abdulazeez was later shot and killed by police.

Smith was shot three times at the Navy Operational Support Center (NOSC) by Abdulazeez. He was struck in the right arm, back and stomach, family members told the Salina Journal, according to the Chattanoogan.

He underwent several surgeries and died around 2:17 a.m. Saturday. Smith grew up in Paulding, Ohio and leaves behind a wife and three young daughters.
