Miami securities broker Richard Pearson has pleaded guilty to wire fraud conspiracy in imprisoned ex-lawyer Scott Rothstein’s $1.2 billion Ponzi scheme.

Pearson, who worked in the same Fort Lauderdale building as the law firm Rothstein Rosenfeldt Adler, could face up to five years in prison after pleading guilty Thursday before U.S. Magistrate Judge William Matthewman in West Palm Beach.
