Prosecutors alleged Thompson had punched a man in a wheelchair over a cigar during a night of heavy drinking and then threatened McIntyre when he intervened.
Kimbrough and Miller are accused of withholding a statement made by Jose Padilla, the man in the wheelchair, that was “inconsistent” with what he previously told police about where the killing took place, Ravitz said.
“That evidence was not turned over to defense counsel,” Ravitz said.
Padilla is in a nursing home and did not testify during Thompson's trial. Prosecutors instead used a written statement from him that claimed he said the stabbings were in the street.
That statement was read to the jury.
Padilla has been interviewed by investigators from the district attorney's office and the public defender's office since the trial. He told them the stabbings occurred in the driveway of Thompson's house.
That would have supported Thompson's self-defense claim, Ravitz said.
“This was a very close case, and this type of evidence could have tipped the verdict in the defendant's favor,” Ravitz said.
Kimbrough is a veteran prosecutor and team leader of the domestic violence division. Miller has been a prosecutor for about three years.
Attempts to reach both prosecutors were unsuccessful Wednesday.
Deason and Ravitz praised Prater for acting quickly to “rectify” the situation.
“For the system of justice to work, prosecutors have to be above board and tell the whole truth,” said Ravitz.
“The suspensions show that Mr. Prater won't tolerate this type of conduct.”
