The Jan. 1 accident resulted in theAvengersstar, 52, suffering “blunt chest trauma and orthopedic injuries,” and breaking 30-plus bones.
However, the PistenBully snow groomer began to slide, causing Renner to “exit the vehicle without setting the emergency brake,” and that’s when the machine began to move sideways down a hill, according to the report.

“Once he was off the PistenBully, he realized it was heading directly toward (his nephew),” the report reads. “He feared the PistenBully was going to hit (his nephew), so he decided to attempt to stop or divert the PistenBully.”
The report states that Renner’s nephew was able to render aid until authorities arrived, as family members called 911.
The report also found that the brake light indicator was not working and “mechanical issues may have been a factor in this accident.”
“Although the PistenBully had some mechanical issues, it is believed based on our mechanical inspection that the parking brake would keep the PistenBully from moving forward,” according to the report.
Renner was airlifted to a local hospital where he underwent emergency surgery the next day, and he now faces a long recovery.
