Krouse is set to leave the medical examiner's office later this month.
The defendant in the death penalty case, Tilon Lashon Carter, was convicted in 2006 for the murder and home invasion robbery of 89-year-old James Tomlin after Peerwani offered key testimony during the trial.
Westfall focused largely on Peerwani’s testimony that the victim was suffocated, which Peerwani later acknowledged was just a possibility and may not have happened at all, according to the judge's finding.
Peerwani also failed to disclose that he found a pacemaker in Tomlin’s chest during his autopsy, which could have suggested he died of a cardiac issue instead of a respiratory one, the judge said.
