After months of mounting coronavirus cases, the federal prison at Fort Dix, New Jersey is reporting its first COVID-19 death. 

Myron Crosby, 58, died Friday at a local hospital, the Bureau of Prisons confirmed to WNYC Monday morning. The Massachusetts native was taken in for treatment 10 days after he tested positive for the coronavirus on Dec. 28. The BOP said Crosby was initially placed in medical isolation and transferred to a hospital when he had trouble breathing.

Crosby, who was obese and had diabetes, had applied for compassionate release due to the pandemic and his poor health. Court records show his request was denied in October. A judge said Crosby—who was convicted for distributing heroin—hadn't served enough of his sentence to deter him from a "habit of criminality."

Fort Dix has one of the worst COVID outbreaks among all federal prisons in the country. While vaccinations began last week, more than half the men at the low-security facility have tested positive for the virus—most of them within the last month.
