DENVER -- CALL7 Investigators have uncovered information that could call into question the credibility of Najibullah Zazi, the man being interviewed by federal agents in connection with an international terrorism investigation, and Zazi's stated reason for traveling to and from Pakistan.

A bankruptcy filing in federal court from March 2009 under the name Najibullah Zazi lists an address in Brooklyn, New York where CALL7 Investigators confirmed the man talking to the FBI has lived in the past. The address is not far from where federal agents raided apartments in Brooklyn early Monday morning.

The bankruptcy filing lists the occupation of the man as "self employed, food vendor." That, according to his lawyer, is the same occupation as Zazi.

"He and another friend in New York own a coffee vending cart," said Zazi's lawyer, Art Folsom, on Wednesday.

In another link, CALL7 Investigators have confirmed that a red van, with New York license plates, parked in front of Zazi's apartment when federal agents searched it Wednesday, is registered to the same Brooklyn, New York address listed in the bankruptcy filing.

The bankruptcy paperwork we discovered includes a question of marital status. That is important because earlier this week Zazi's lawyer told the CALL7 Investigators that Zazi is married.

"Mr. Zazi is married to a young woman who lives in Pakistan and he travels there about once a year in order to see her," Folsom said in an interview on Wednesday.

But that is not what it says in the bankruptcy filing that lists the Brooklyn address. On two separate pages, the marital status is marked as "single" and "unmarried." The bankruptcy filing is on a sworn document in U.S. Federal Court filed in March of this year.

According to Folsom, Zazi has been trying to get his wife into the United States for several years under a program to help Afghan citizens who want to come to the U.S.

"He tried to get her into that program in 2006. I believe in August 2006. He applied for that and wasn't able to get her into the program," Folsom said.

Zazi has been with federal agents most of Thursday and we have not been able to ask him or his attorney specific questions about the bankruptcy, which included a list of 20 creditors, mostly credit cards.

In the bankruptcy filing, 15 of the 20 accounts were opened in 2008 between March and August. Bankruptcy was filed less than a year later, after the filer racked up more than $50,000 in debt to places such as Sony, Best Buy, Macy's and gas cards.

The use of multiple credit cards is important because in terrorism investigations it can be a red flag that can lead investigators to patterns of spending in short periods of time.

Those patterns can leave a trail for agents to follow.
