Glenn Lewellen, 55, retired from the department in 2002 and has denied all charges.
In testimony Thursday in federal court, a member of the drug-trafficking crew testified Lewellen tortured a drug dealer to force him to say where he was stashing his money, the Chicago Sun-Times reported.
Drug ring leader Saul Rodriguez has pleaded guilty to charges including racketeering and murder in aid of racketeering. He is expected to testify against Lewellen, the Chicago Tribune said.
