input: LOS ANGELES - Jesus Ibarra was puzzled by the elderly man.

He was obviously much older than other students at prefix = st1 /CentralAultHigh School. And he was an Anglo on a campus where most students are Latins, Blacks, and Asian - Americans.

"I asked myself what he was doing here," said Ibarra, 21, of Los Angeles. "I thought he was a visitor. The first time I talked to him, I asked a question in English, and he answered in Spanish. I thought he was white and Jewish. I never imagined that he would speak Spanish."

Jacob Blitzstein surprised his fellow students all the time. He isn't some _ man, though he wears his neat gray beard and conservative (traditional) clothes.

Blitzstein is warm and gregarious (enjoys being with others). He likes to hear a good joke and loves to tell a good story. He is determined, especially when it comes to realizing his dream.

Recently, that dream came true. At a graduation ceremony attended by two of his children and three grandchildren, Blitzstein, 81, graduated from high school.

After Principal Lanny Nelms handed him the diploma and announced his age, Blitzstein waved to the audience and cried.

And why not? He's probably the oldest CentralHigh Schoolgraduate since the school opened in 1974. According to theLos Angelesdistrict spokesman, although no records of such things are kept, Blitzstein is the oldest graduate he's ever heard of.

Earning his diploma took 10 years, during which the retired store owner suffered heart attack and ill health, and lost his wife and two brothers.

He kept to his task for a reason. "School is the best medicine you can have," he said. "You have something on your mind - a goal."

With his diploma in hand, Blitzstein states that _ .

"You know something ? I'm going to college," He told a visitor recently. He has checked out West Los Angeles and Santa Monicacommunity colleges and hopes to move from there to a four-year school.

"It's not a joke," he said. "If I live to the year 2008, maybe I'll be a doctor." 1. Who puzzled Jesus Ibarra?

input: (CNN)His voice, his posture and his threats are menacingly familiar.

The black-clad ISIS militant shown in a video demanding a $200 million ransom to spare the lives of two Japanese citizens looks and sounds similar to the man who has appeared in at least five previous hostage videos.

The knife-wielding masked man with a London accent, nicknamed "Jihadi John," has issued threats and overseen the beheadings of American and British captives.

"You now have 72 hours to pressure your government in making a wise decision, by paying the $200 million to save the lives of your citizens," the man in the video that appeared Tuesday says in comments addressed to Japanese citizens. "Otherwise, this knife will become your nightmare."

Q&A: Harsh realities of kidnappings, ransom

The amount of money is the same as that recently pledged by Japanese Prime Minister Shinzo Abe in humanitarian aid to Middle East countries that are affected by ISIS' bloody campaign in Iraq and Syria.

Japan believes the deadline arrives Friday at 12:50 a.m. ET. And Chief Cabinet Minister Yoshihide Suga said Wednesday the country will do its best to communicate with ISIS through a third-party nation.

But mystery and confusion still surround the identity of Jihadi John.

U.S. and British officials have said they believe they know who he is, but they haven't disclosed the information publicly.

That could be because Western intelligence agencies believe they have more to gain from keeping quiet, says Aki Peritz, a former CIA officer.

"They can put pressure on his family, put pressure on his friends," he told CNN. "Maybe they have a line to him. Maybe they know who his cousins are who are going to Syria who can identify him. However, if you publicly tell everybody who he is, his real identity, then maybe he'll go to ground and he'll disappear." 1. who had a accent ?
