Jeremy Renner was trying to save his adult nephew from being crushed by his snowplow when it accidentally ran him over according to a Nevada sheriff’s office incident report.

According to Washoe County Sheriff’s Office report obtained by CNN, the Avengers actor reportedly had not activated the emergency brake when the machine started sliding sideways after he had used it to pull his nephew’s truck out of the snow.

“The Pistenbully snow groomer began sliding causing Renner to exit the vehicle without setting the emergency brake. 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. When Renner attempted to stop or divert the Pistenbully to avoid injury to (his nephew), he was pulled under the vehicle by the track and run over,” the report concluded.

The report also noted that the brake indicator light inside the snowcat’s cab was not functioning, and “mechanical issues may have been a factor in this accident.” The officials also added that impairment was not believed to be a factor in the incident.

The horrifying accident occurred on New Year’s Day when the 52-year-old actor towed his nephew’s truck off the actor’s driveway after it had been stuck in the snow.

After nearly two weeks in the hospital, he returned home earlier this month- later revealing he had broken more than 30 bones in the freak crash.

Renner posted a picture on Instagram last week of him on a bed, aided by his doctor, “Morning workouts, resolutions all changed this particular new years …. Spawned from tragedy for my entire family, and quickly focused into uniting actionable love. I want to thank EVERYONE for their messages and thoughtfulness for my family and I …. Much love and appreciation to you all. These 30 plus broken bones will mend, grow stronger, just like the love and bond with family and friends deepens Love and blessings to you all.”
