An inquest that will examine events surrounding the death of an inmate at the Windsor jail is now underway.

Approximately 15 witnesses will speak before a Windsor court over the course of five days, to examine the death of 26-year-old Johnathon Dew.

Dew died shortly after collapsing in his cell on Sept. 21, 2012. A coroner determined that Dew suffered a heart attack. He was rushed to a London hospital, where he died.

At the end of the inquest, a jury may make recommendations on how to prevent similar cases from happening in the future.
