The Atlanta Braves are being sued by the widow of a man who died in a walk-in beer cooler at SunTrust Park – a death her lawyers attribute to problems in the cooler known to the Braves prior to the incident.

Marvin Todd Keeling, a beer tap inventor, died while installing beer taps in a cooler at SunTrust Park on June 26, 2018. According to news reports, the wrongful death lawsuit filed by Angela Keeling asserts that her husband was unable to escape the cooler when it unexpectedly filled with carbon dioxide because of a faulty door mechanism.

An autopsy determined that the cause of death was carbon dioxide poisoning.

The lawsuit reportedly notes that the Braves’ management was notified about a problem with the door release mechanisms in the stadium’s coolers via email, prior to Keeling’s death. Several construction and beverage service companies were also named in the suit.

Angela Keeling is seeking unspecified damages.

The Braves have not released a statement on the suit.
