After decades-long "unsolved mystery," Illinois sailor killed at Pearl Harbor to be laid to rest

Herbert "Bert" Jacobson will be laid to rest on Tuesday, more than 80 years after he was killed in the attack that propelled the United States into World War II.

Members of Jacobson's family have waited all their lives to attend a memorial for the young man they knew about but never met. Jacobson was among the more than 400 sailors and Marines killed on the USS Oklahoma during the Dec. 7, 1941, Japanese attack on Pearl Harbor. The casket containing his remains will be interred at Arlington National Cemetery.

"This has kind of been an unsolved mystery and it gives us closure to finally know what happened to Bert, where he is and that he's being finally laid to rest after being listed as an unknown for so long," said Brad McDonald, a nephew.
