The central figure in a huge New Jersey corruption investigation pleaded guilty to federal bank fraud and money laundering charges Tuesday.

Solomon Dwek's work for the government as a cooperating witness directly led to the arrests of 44 people in July, but it was his turn in court Tuesday.

Wearing a dark suit and light blue tie, the 37-year-old Dwek stood before U.S. District Judge Jose Linares and admitted his role in a multimillion-dollar bank fraud scheme in 2006. He acknowledged depositing two $25 million checks drawn on a closed account and using them to make wire transfers to separate banks totaling nearly $23 million.

Bank fraud carries a maximum prison sentence of 30 years, and the maximum for money laundering is 10 years, but Dwek would face nine to 11 years under federal sentencing guidelines. Linares can adjust that range up or down when he sentences Dwek on Feb. 9, and the U.S. attorney's office said it may recommend a lighter sentence based on Dwek's ongoing cooperation.
