When Marc Fliedner, a candidate for Brooklyn District Attorney, summoned reporters to a Friday-evening “emergency press conference” to be staged outside the Louis H. Pink Houses in East New York last week, it was with the promise of the sort of eleventh-hour bombshell that could overturn the campaign. “Marc will be exposing all mounting evidence of corruption in the administration of Acting District Attorney Eric Gonzalez,” blared the press release. That was a considerable oversell.

At the press conference, Fliedner mostly rehashed his campaign’s bill of indictments against Gonzalez, who is also running for District Attorney. The only fresh information presented was that Fliedner intends to sue Gonzalez for slander, and that Fliedner himself is named as a defendant in a new federal lawsuit stemming from allegations of misconduct when he was a prosecutor in the Brooklyn DA’s office.

Both lawsuits stem from the same episode, one that raises the possibility that the Brooklyn DA’s efforts to grapple with its history of convicting innocent defendants has itself been politicized. Fliedner quit as head of the DA’s Civil Rights Bureau last year in protest after he won a conviction of Peter Liang, the police officer who shot and killed an unarmed 28-year-old, Akai Gurley, in a stairwell of the Pink Houses. Following the conviction, Fliedner’s boss, Brooklyn DA Ken Thompson, overruled him and opted not to ask for any jail time for Liang, who ultimately got off with probation and community service.

“I was so offended by that I left and talked to the Daily News my first day off from work,” Fliedner recounted Friday. “Two days later, Eric Gonzalez authorized a letter going to the New York Times saying that in one of our conviction review cases, it looks like some evidence was withheld and Marc Fliedner did it. Really? Two days later? What a shock.”

The Brooklyn DA's office declined to comment on the record. Gonzalez's campaign has not responded to our requests for comment on Fleidner's accusations, but we'll update if they do.

Thompson had earned praise for his Conviction Review Unit, which has so far overturned the convictions of 22 people in Brooklyn. But the timing of the press announcement from Gonzalez, then Thompson’s deputy, that Fliedner had prosecuted a case in which critical evidence was withheld from the defense, smacked of political payback. Fliedner, who didn’t inherit the 2005 murder case until 2008, claims he gave the defense everything he was supposed to. “It becomes clear now that before I got to that case, some pieces of evidence were hidden,” he said Friday.

Since Thompson died of cancer last year and Gonzalez took over as Acting District Attorney, he has kept up the attack on Fliedner. “You failed to turn over the material, it’s a wrongful conviction,” Gonzalez told Fliedner at a candidate’s debate in July. “That is a lie,” Fliedner said Friday. “I am going to file a lawsuit against Eric Gonzalez personally as a campaigner who told a lie, for slander.”

Last week Wayne Martin, the man convicted in the 2005 murder case, filed a federal lawsuit against the City of New York, the police detectives on his case, and Fliedner.

What impact all of this back and forth will have on the primary election Tuesday is anybody’s guess. There has been little public polling on the race, though a private poll reported on by City Limits in late August showed Gonzalez leading the six-candidate pack with 19 percent support, followed by Vincent Gentile at 14 percent and Flieder at 10. But the poll also showed a full 42 percent of those surveyed were undecided, leaving the race wide open.

Since then, the New York Times has endorsed Gonzalez, which is likely to help him cement his lead. But two days later a close analysis by the Five Borough Defenders, an association of public defenders who advocate for criminal justice reform, gave Gonzalez an unimpressive C+ on policies that will help end mass incarceration. Gentile earned a D+ in the report, while Fliedner earned the top score, with an A-.

There are no Republicans running for Kings County District Attorney, which means the winner of Tuesday’s primary will be the next DA. Polls will be open from 6 a.m. to 9 p.m. You can find your local polling place here.
