Vitas Gerulaitis Champion tennis player
On September 17, 1994, while visiting a friend’s home in Southampton, New York, an improperly installed propane heater for the swimming pool caused carbon monoxide gas to seep into the guesthouse where Gerulaitis was sleeping, causing his death by carbon monoxide poisoning.
Back in the 2009 ice storm, over 400 people in KY were reported with carbon monoxide exposure. 10 people died of it.
