A male Navy Petty Officer became the fifth U.S. service member to have died following a shooting at the Navy Operational Support Center in Chattanooga, Tennessee on Thursday.

"A male Navy Petty Officer succumbed to wounds received in the July 16 shooting at the Navy Operational Support Center (NOSC) in Chattanooga, Tennessee July 18 at 2:17 a.m.," reads a statement issued by the U.S. Navy Office of Information on Saturday.

"In total, four U.S. Marines and one Sailor were killed in the incident," states the press release, adding that his name will not be released until 24 hours after the victim's family has been contacted.

However, media outlets have already identified the fallen sailor as 26-year-old Petty Officer 2nd Class Randall Smith, according to USNI News.

The other four slain Marines have been identified as Thomas Sullivan of Massachusetts, Squire "Skip" Wells of Georgia, David Wyatt of North Carolina, and Carson Holmquist of Wisconsin, reports CNN.

The incident began Thursday morning when a gunman identified as Mohammad Youssuf Abdulazeez opened fire at a military recruiting center at a strip mall on Lee Highway.

The shooter then drove a rental car to the Navy operational support center about seven miles away, where the four Marines were killed at a Naval recruiting station in Chattanooga, reports NBC affiliate WBIR.

Chattanooga Police Chief Fred Fletcher said that police followed and engaged Abdulazeez at two different locations.

Abdulazeez, who graduated from the University of Tennessee at Chattanooga, kept police at bay for some time before he was killed.

"All indications are he was killed by fire from the Chattanooga police officers," Reinhold told reporters Friday. "We have no evidence he was killed by self-inflicted wounds."

FBI agents are still looking for the suspect's motive. Reinhold said the 24-year-old engineering graduate was not tied to a known terrorist organization, nor was he very active on social media.
