DENVER -- Najibullah Zazi's boss and the owner of 1st ABC Shuttle described Zazi as a quiet guy who wanted to work hard and simply make money.

Zazi is one of three men charged with lying to federal agents in an investigation involving a possible terrorist plot.

The owner of 1st ABC Shuttle did not want to talk on camera and told CALL7 Investigator Tony Kovaleski that he has recently been the victim of unwelcome contact. He said he fears for his safety and the safety of his family.

He also said that someone damaged one of his shuttle vans, so for protection the company, he spoke to 7NEWS through attorney Richard Gross.

Talking about Zazi, Gross said, "It was our understanding that he had a wife in Pakistan and he was supporting quite a few people here in Aurora and he was sending money back to Pakistan."

Gross explained that Zazi was given the job with 1st ABC Shuttle because his uncle was working there and the uncle was a distant cousin of the owner.

"We had no idea that he was under anybody's watch or that he was a suspect in anything. He stayed pretty much to himself, worked long hours -- 80 hours a week -- and he was interested in making money," said Gross who also confirmed that Zazi had cleared two background checks -- one by the city of Denver and one by Denver International Airport.

Zazi began working for 1st ABC Shuttle as an independent contractor in March and, according to Gross, the only issue to ever come up was Zazi's beard.

"The airport authorities would give him a difficult time because of his beard. Evidently they felt that his beard was off-putting to some clientele and wasn't something they encouraged," Gross said.

"Were there any red flags, any warnings before hiring Mr. Zazi?" Kovaleski asked Gross.

"None whatsoever, otherwise he wouldn't have been hired."

"It seemed like his most important goal was to work as many hours and make as much money as possible, "said Gross. "And that's why this whole episode comes as a shock to his associates at 1st ABC and the owners of 1st ABC. It came as a complete surprise."

A surprise because the owner of 1st ABC told Kovaleski that Zazi never shared any anti-American beliefs and never discussed any kind of attack or terrorist plot.

"The folks that own 1st ABC are Americans, they are citizens, and they're hardworking and they don't condone any type of terrorism anywhere. And that's the message we want to get out. They're decent people that own the company," said Gross.
