A man injured in a racing accident at Heartland Park Topeka last month has died.
Racinboys.com reports 43-year-old John Hefferon junior was injured October 25th.
They say he passed away at Stormont Vail last Friday, where he'd been since then.
Hefferon was competing in a race when he hit a wall during a turn and his car flipped. Racinboys says no other cars were involved in the accident.
