AP investigation finds gunshot detection technology has helped send innocent people to jail
Michael Williams sits for an interview in his South Side Chicago home, July 27, 2021, after spending nearly a year in jail as a suspect in a May 2020 killing. Prosecutors had used ShotsSpotter evidence to build their case against Williams. “I kept trying to figure out, how can they get away with using the technology like that against me?” he asked. “That’s not fair.” His case was eventually dismissed when prosecutors said they had insufficient evidence.

For months, investigative reporters Garance Burke, Martha Mendoza and Juliet Linderman had been digging into a controversial tech tool favored by police, an algorithm-powered gunshot detection system they learned was being used as evidence in criminal trials that helped send innocent people to prison.

The trio contacted dozens of defense attorneys nationwide, pored over thousands of documents, including confidential material from the California-based company ShotSpotter, and built relationships with sensitive sources, including Michael Williams, a 65-year-old grandfather who had just spent nearly a year in a Chicago jail. Williams’ attorneys contacted Burke exclusively to let her know that he was about to be released after prosecutors dropped their murder charge against him. The reason? The ShotSpotter evidence prosecutors used to build their case was “insufficient.”

Jacqueline Anderson watches as her husband, Michael Williams, takes their dogs out in the backyard of their home on the South Side of Chicago, July 27, 2021. Anderson said that for days after the May 2020 fatal shooting of 25-year-old Safarian Herring in Williams’ car, Williams curled up on his bed, having flashbacks and praying for his passenger. – AP Photo / Charles Rex Arbogast

On his first night after release from the Cook County Jail, Williams couldn’t eat on his own. He’d beaten COVID-19 twice while in jail, but developed an uncontrollable tremor in his hand that kept him from holding a spoon. So his wife Jacqueline Anderson fed him. And as they sat together on the couch, she held onto his arm to try and stop the shaking. – AP Photo / Charles Rex Arbogast

Shooting victim Safarian Herring of Chicago is shown in an undated family photo. Samona Nicholson, Herring’s mother, said he once studied at Le Cordon Bleu culinary school and dreamed of starting a food-truck business. Two weeks before being fatally shot in May 2020, he had survived a shooting at a bus stop. Nicholson believes police had the right suspect in Michael Williams; she blames ShotSpotter for botching the case. – Courtesy of Samona Nicholson via AP

That break became the basis for the first investigation in a new series called “Tracked,” funded by the Pulitzer Center on Crisis Reporting. Burke and Linderman hurried to Chicago for the first of a series of interviews with Williams at his Chicago home, which put a human face to a story about inanimate algorithms that can change the course of people’s lives.
Legal affairs reporter Michael Tarm joined the effort, obtaining records through the Freedom of Information Act and sources, and securing an interview with the family of the man Williams was accused of killing. With footage shot by Chicago video journalist Teresa Crawford and photos by Charlie Arbogast, producer Serghino Roosblad edited a moving minidocumentary about Williams’ life and struggles following his release.
The resulting story was picked up by hundreds of outlets,including the major Chicago papers. Even amid news from Afghanistan and the Capitol bomb threat,this was among the most-read stories on AP News,netting more than 158,000 pageviews.
Sen. Ron Wyden,R-Ore.,asked the Justice Department to look into whether ShotSpotter and other technologies contribute to bias in policing. The Chicago Sun-Times published an op-ed demanding that ShotSpotter evidence not be used in court. The AP team was interviewed about their findings,including by CBS News and WVON News,an influential Chicago talk radio station focused on the African American community.
For dogged document research,delicate source work,nimble reporting and all-formats collaboration,the team of Burke,Mendoza,Linderman,Tarm, Crawford and Arbogast and Roosblad is first runner-up for AP’s Best of the Week award.
