Staffing at the St. Louis Metropolitan Police Department dropped by about a third since 2014. There’s a backlog of DNA samples linked to homicides, and the homicide squad grappled for resources as murders in the city spiked. Our investigation with APM Reports and The Marshall Project has found that one reason police failed to solve more than 1,000 homicides in the city over the last 10 years is a lack of resources. Tom Scheck with APM Reports, spent a lot of time digging into the finances of the SLMPD’s homicide squad. He spoke to St. Louis Public Radio's Rachel Lippmann about the findings.
