Bell's relationship with Kilpatrick is a small but significant part of the government's case against the ex-mayor. Kilpatrick's father and two other people are also on trial. An alternate juror was dismissed Thursday, leaving four alternates in a trial that is expected to extend into 2013.
Kilpatrick, whose mother is former U.S. Rep. Carolyn Cheeks Kilpatrick, was elected mayor in 2001. He resigned in 2008 and pleaded guilty to obstructing justice by lying in a civil case about having sex with an aide. He subsequently served 14 months in prison for violating his probation in that case.
