It took six years and a detour through Beverly Hills, but on Friday, federal prosecutors in Los Angeles finally got their first guilty plea in the long-running investigation of the class action plaintiffs firm Milberg Weiss Bershad & Schulman.

And it looks to be a significant one: in saying that he and his family took nearly $2.5 million in illegal kickbacks from Milberg Weiss in exchange for serving as lead plaintiffs in several class actions, Howard Vogel fingered four partners at the New York firm and agreed to cooperate in the ongoing investigation.
