Las Vegas: Mortgage Fraud Ground Zero

Prosecutors have charged Eve Mazzarella, 30, and Steven Grimm, 45, with bank fraud, alleging the two caused banks to make more than $107 million in dubious loans and netted a profit of at least $15 million. Both defendants pleaded not guilty to the charges. A trial has been scheduled for October.

To the untrained eye, the size, scope and sophistication of the alleged scheme is noteworthy. But to the FBI in Las Vegas, the problem is the opposite: In recent years, there have been so many mortgage fraud cases, the bureau and local prosecutors have had to establish a special task force to combat the problem.
