A 60-year-old Michigan, United States inmate who was sentenced to life in prison as a juvenile died from coronavirus three weeks before he was set to be released, the Detroit Free Press reported.

William Garrison had spent 44 years in prison on a first-degree murder conviction, connected to a shooting that happened when he was 16, in 1976.

He was set to be released first week of May. But he died from COVID-19 on April 20 in the prison.

Garrison had not complained of any symptoms to his family or the prison staff, but a postmortem test confirmed that he had the virus.
