The Daily Herald reports Jeffrey Bronken's inadequate fuel planning, which resulted in a total loss of engine power, led to the crash. "The pilot's impairment due to cocaine use" contributed to the crash, according to a National Transportation Safety Board probable cause report.
The March 22, 2014 crash killed Bronken and his 15-year-old daughter Katherine, who died of her injuries four days later. Katherine's 15-year-old friend, Keyana Linbo, survived the crash. Both attended Grant Community High School and were on spring break at the time.
Bronken's Piper Fixed Wing single-engine plane nose-dived into a six-lane road near the Clearwater airport after taking off from Campbell Airport in Grayslake, Ill. The plane hit power lines before crashing head first into a median.
Bronken was a glass contractor who owned The Glass Man Inc., formerly known as Inman Glass. FAA records show the plane that crashed was owned by Bronken's Highland Park business.
