The NASCAR fan killed by a lightning strike at a track in northeastern Pennsylvania was a 41-year-old man from a nearby county, authorities said Monday.
Brian Zimmerman, of Moosic, Pa., died as he stood near his car in the parking lot of Pocono Raceway, according to the Monroe County coroner. A woman who answered the phone at Zimmerman's home declined comment.
Nine other people were injured during Sunday's violent storm, though it wasn't immediately clear how many might have been struck by lightning. One who had been listed Sunday night in critical condition was upgraded to stable.
The crowd of about 85,000 was advised over public address systems and through social media to take cover Sunday afternoon when lightning and heavy rain hit the track near the end of the race. But some fans posted on the raceway's Facebook page that they never heard the weather-related announcements.
NASCAR spokesman Dave Higdon said Monday that officials are reviewing how the track carried out its emergency procedures. He cautioned against rushing to judgment until all the facts are known.
''Anytime something like this happens, we make sure we look at it again and see if there's anything we should have done different,'' Higdon said. ''It's never a good day for us when someone passes and people are hurt.''
Pocono Raceway president and CEO Brandon Igdalsky expressed sorrow at a news conference Monday afternoon at the track, where a large U.S. flag flew at half-staff.
''Fans are like family to us,'' Igdalsky said, noting that Zimmerman had been coming to races for several years with his friends. He added that he planned to contact Zimmerman's family and visit other victims.
Pocono officials are going through log books to establish a timeline for the storm, weather warnings and final laps of the shortened race, Igdalsky said.
One bolt hit the grandstand parking area around 5 p.m. Sunday, killing Zimmerman and injuring eight others, Igdalsky said. A second possible strike came around 6:35 p.m., sending a ninth person to the hospital with minor injuries, he said.
