A 20-year-old man biking in Maryland has died after going into cardiac arrest and authorities suspect heat could
be a factor.
Prince George's County Fire and Rescue officials say the man seemed to have gone unconscious while biking around 11:15 a.m.
They say witnesses saw the man hit his head on a tree as he fell from his bike.
Paramedics found the man in cardiac arrest and displaying possible signs of heat-related illness.
They took him to Fort Washington Hospital Center but he died shortly after arriving.
Paramedics said in a press release that high temperatures and humidity ``more than likely'' played a role in the death. Area
temperatures were in the 90s when the incident occurred.
