Massive mortgage fraud case ends

US Attorney Carmen M. Ortiz said the investigation and prosecution required extensive governmental resources and should put the lending and real estate industry on high alert. “If you engage in fraud in order to line your pockets at the expense of others, we will spare no expense investigating and prosecuting you,’’ Ortiz said.

Appolon was convicted of charges related to two properties, in South Boston and Dorchester, for which he allegedly inflated sale prices negotiated with sellers by as much as $80,000. Prosecutors said he pocketed more than $150,000 in illegal profits.

Appolon’s lawyer, Derege B. Demissie of Cambridge, said he plans to file an appeal, arguing that some of the fraudulent loan documents attributed to his client were created and submitted by others.

The sentencing wraps up the case against a dozen defendants including lawyers, a real estate broker, and loan officers who were charged with recruiting stand-in buyers whose names and credit information were used to purchase homes they never planned to live in.

Earlier this year, Eric L. Levine, a former Brookline lawyer described by federal prosecutors as the leader of the scheme, was sentenced to 12 years in jail.

Other defendants in the case received sentences ranging from probation to 87 months in prison.
