Monday briefing: What a new Guardian podcast reveals about the US justice system

In today’s newsletter: Off Duty revisits the conviction of Alexander Villa, raising troubling questions about how it was built

Good morning. On the evening of 29 December 2011, Clifton Lewis – an off-duty Chicago police officer working as a security guard at a minimart on the city’s west side – was shot dead during a robbery. The killing prompted a huge manhunt and an intensive investigation by the Chicago police department. Years later, prosecutors said they had their man, and in 2019 Alexander Villa was convicted of Lewis’s murder and sentenced to life in prison.

But the case against Lewis has long been contested – and as the Guardian’s new investigative podcast series, Off Duty, explores, there are troubling questions about how that conviction was secured, from confessions that were later recanted to evidence that appears shaky or missing. And it revolves around a justice system that, once it settled on a suspect, seemed unwilling to reconsider.
