What improves the chances of solving a murder?

Not living in Oakland County, for starters. An article in today’s NYT examined the clearance rate for murders and the common belief that chances for solving a murder start to evaporate after 48 hours. https://www.nytimes.com/2021/07/23/upshot/murder-crime-solving.html.

“Unsolved murders and nonfatal shootings means justice denied to the victims of those crimes and their families,” said Justin Nix, an associate professor in the School of Criminology and Criminal Justice at the University of Nebraska at Omaha. “A low clearance rate, especially for these most serious of crimes, might be interpreted by community members as a signal that the agency (1) doesn’t care about or (2) is not very good at keeping them safe.” This can lead to retaliatory violence instead of cooperation with the police, he said.
