The death of an electrical worker who fell 75 feet at Little Caesars Arena in Detroit was accidental, according to the Wayne County Medical Examiner's Office.

Michael Morrison died of multiple injuries in the Wednesday morning fall, said Lisa Croff, director of Communications & Media Relations for the Wayne County Department of Health, Veterans & Community Wellness.

Detroit Police Media Relations Director Michael Woody said earlier in the week that investigators believe the death was a suicide, based in part on the statements of witnesses.

Croff said the accidental ruling was based on Morrison's injuries. That could change as the police investigation unfolds, she said.

The Detroit Fire Department was dispatched to the arena construction site at 8:03 a.m. Wednesday. A fire department official said Morrison went into cardiac arrest.

He was pronounced dead at Detroit Receiving Hospital.
