Chronic alcohol abuse was confirmed as the cause of Adam Zimmer’s death.
Minnesota’s Hennepin County Medical Examiner’s Office announced the news on Friday, according to multiple outlets.
The Cincinnati Bengals, where Zimmer was an assistant coach, first announced his death in a statement on November 1.
Last month, the Mendota Heights Police Department conducted a social screening on Zimmer, who lived in Minnesota, Police Chief Wayne Wegener Jr. said, according to ESPN.
By the time police reached Zimmer’s home, he was already dead. At the time, Wegener said authorities “would not be investigating this as a suspicious death,” and the Hennepin County Coroner would rule on his cause of death and release it.
A week after Zimmer’s body was found, the Minnesota Star Tribune reported that an affidavit with a search warrant filed by police said they had received an alert about a man who was unconscious, having possibly been drinking excessively. When they arrived, they discovered Zimmer dead on a couch, according to the outlet.
Police filed the affidavit in Dakota County District Court and said Zimmer also suffered an eye injury Star Tribune.
Zimmer “appears to have bruising or pooling of blood around his eye,” officials wrote pioneer press. In their file, the police said they suspected no third-party fault Star Tribune reported.
Zimmer, whose father is longtime NFL coach Mike Zimmer, began coaching the Bengals this season. Before that, he was a coach for the Minnesota Vikings after his father became the head coach in 2014. He and his father were fired last year, according to ESPN.
Adam’s first coaching position in the NFL was in 2006 as an assistant linebackers coach for the New Orleans Saints.
The Hennepin County Medical Examiner’s report lists his official cause of death as “complications of chronic ethanol use disorder.”
Zimmer began his NFL coaching career in 2006 as assistant linebackers coach for the New Orleans Saints, where he won a Super Bowl. He transitioned to the same role for the Kansas City Chiefs in 2010.
In 2013, he became assistant defensive backs coach for the Bengals. He worked for the Vikings from 2014-2021, including a two-year stint as co-defensive coordinator before his father was fired at the end of the 2021 season.
The Bengals released the following statement shortly after Zimmer’s death:
“Our organization has had the privilege of knowing and working with the Zimmer family for 15 years. We have the highest regard for Mike and Adam, and we are incredibly saddened by this tragic news. Mike and Adam were more than just coaches for us – they were friends. Our thoughts and prayers are with the Zimmer family at this time.”
