Fifty-eight-year-old Dennis Deska was arrested after throwing a flower pot through the window of a diner and crashing into a police car. He has a history of severe mental health issues, as well as other physical problems, but he hasn’t been taken to a psychiatric hospital. Instead, he’s sat in jail for almost 10 months without a preliminary hearing. Why has this happened to Deska? And how does his case reflect a broader mental health crisis in Pennsylvania? Philadelphia Inquirer reporter Samantha Melamed and host of WHYY’s The Pulse, Maiken Scott join us on this episode of The Why.
