The Hennepin County medical examiner has determined that amateur bodybuilder Erik Fromm died from an accidental overdose of Fentanyl. Fentanyl is a highly potent painkiller described as 80 times as strong as morphine. Fromm was in a severe car accident that resulted in severe pain.

Fromm had a serious traffic accident about a year ago in Wyoming, causing him severe pain in his lower back and in his legs and arms, said Kevin Schreifels, a friend of Fromm’s.

“He was rating the pain pretty high,” said Schreifels, a doctor at Lyn-Lake Chiropractic in Minneapolis. He said he was unaware of Fromm using fentanyl.
