U.S. Attorney Andre Birotte Jr., San Bernardino County District Attorney Michael Ramos and Riverside County Assistant District Attorney Creg Datig were among the speakers.
"The Inland Empire is leading the nation in home foreclosures," Birotte said. "And that is fuel for some of the less than honorable people to take advantage of those in perilous situations."
San Bernardino County is leading the state in prosecutions that stem from this type of fraud, Ramos said.
In recent months the U.S. Justice Departement has arrested dozens of Inland Empire men and women suspected of scamming financially distressed homeowners.
Many of the homeowners lost their homes and life savings, authorities said.
In September, federal authorities arrested a Rancho Cucamonga woman - Andrea Ramirez - who operated 21st Century Real Estate Investment Corp. and several other companies.
According to the indictment, employees allegedly defrauded financially distressed homeowners by making false promises and guarantees about their ability to negotiate loan modifications from the homeowners' mortgage lenders.
Ten others were arrested in that scandal.
"I am very proud to say that we are leading the state in prosecuting real estate fraud," Ramos said.
But he said state legislation to relieve overcrowding in the state prison system is a direct threat to law-abiding citizens.
"These felons are taken from the state prison system and put in the local county jails," Ramos said. "The jails are overcrowded and not built to sustain prisoners for that length of time."
So they are released and find new ways to commit fraud on unsuspecting citizens, he said.
"That's why meetings like this are so important," Ramos said. "We are tasked with the job of being the voice for the victims, and the more we learn from each other, the louder we become."
The Riverside County District Attorney's Office has a special unit consisting of three prosecutors and four investigators to fight this type of crime.
"This fraud is like a cancer eating away at the law-abiding citizens of the Inland Empire," said Datig. "We are not just working as individuals to end this devastating criminal act, but as an entire community to bring justice to the criminals."
