Deserved or not, Leakin Park has a reputation. Scores across the country know it as the site where Hae Min Lee was buried in a shallow grave, a case probed years later on the podcast “Serial.” Locals better know Leakin Park as the densely overgrown expanse in their backyards with a host of possibility but also insufficient staffing, illegal dumping and safety concerns. Recently, however, there has been movement to improve Leakin Park’s circumstances, making it more of an asset for the historically disinvested West Baltimore neighborhoods that surround it.
