AURORA | A U.S. Navy sailor from northern Illinois was among those killed by a gunman at a Colorado screening of the new Batman movie.

The parents of John Larimer released a statement that Navy officials notified them about midnight that their 27-year-old son was one of the 12 killed.

Friday’s mass shooting took place at a movie theater in the Denver suburb of Aurora.

The family says that Larimer’s brother Noel is working with the Navy to bring his body back home to Crystal Lake, Ill.

The Navy says another sailor was treated and released for injuries sustained at the theater. Both were from a unit that belongs to U.S. Fleet Cyber Command/U.S. Tenth Fleet at Buckley Air Force Base.

Larimer is the fourth victim identified by family members so far.
