There is another twist in the Kirk Zimmerman murder case. The Pantagraph reports that Zimmerman recently filed documents, asking for half his bond money to be returned, so he can fund expert witnesses needed for his defense. Zimmerman is accused of murdering his ex-wife, Pamela, inside her Bloomington business in November 2014. The paper reports that the funds would help hire expert witnesses, which would analyze and testify about evidence, which they say includes gunshot residue allegedly found on the gear shift of Kirk Zimmerman's car. It is unclear when a judge will rule on the motion.
