Baltimore medical examiner's office investigating death of fan during playoff game

The Baltimore medical examiner's office has opened an investigation into the death of a Ravens fan after he fell in the upper deck of M&T Bank Stadium on Saturday, an agency spokesman said, according to the Baltimore Sun's Justin Fenton and Phillip Jackson.

Examiners are looking into circumstances of the incident and toxicology tests have been conducted.

"We can confirm there was an incident last night at the stadium where a fan collapsed while walking on the steps of the upper deck," Ravens spokesman Chad Steele said Monday, according to Jonas Shaffer of the Baltimore Sun. "Medical personnel arrived quickly, but attempts to resuscitate him were unsuccessful."

Mike Kahler, 30, stumbled on the steps leading to his seat, Steele said in an email, according to Lillian Reed of the Baltimore Sun.

Steele added that security footage showed S.A.F.E. Management, the company that provides the stadium's ushers and security, reported the incident less than two minutes after the stumble. About 15 minutes later, Kahler was taken to Maryland Shock Trauma.
