MARTINEZ (KCBS) – A Contra Costa County prosecutor has filed a claim against his bosses in the district attorney’s office, claiming malicious prosecution and defamation as a result of rape charges against him.

55-year-old Michael Gressett said his troubles started three and a half years ago when he took sides in a bitterly fought race for district attorney.

KCBS’ Bob Melrose Reports:

He was accused of rape and fired following a daytime visit with a colleague to his Martinez apartment in May 2008.

Gressett said that the sex was consensual. Last year the firing was overturned and the rape charges were dropped.

Speaking for the first time on Wednesday about the charges that were filed against him, Gressett said he was depressed, had thoughts of suicide and wants one thing:

“The ultimate satisfaction for me will be a trial, more so than a settlement,” Gressett said. “A trial where all these people have to testify, they are cross-examined extensively and people can see what I’ve been saying for years. It started when I ran for DA when I told you there was corruption amongst these people. And no one seems to want to talk about it.”

The Contra Costa County District Attorney’s Office, County Counsel and Martinez Police Department, all named in the claim, did not return calls seeking comment.

Gressett’s attorney said he has been reinstated but remains on paid administrative leave.
