More details are being uncovered in the investigation into Bob Bryar‘s death.

Over three months after he was found dead in his Tennessee home at age 44, the Bedford County medical examiner revealed that the former My Chemical Romance drummer’s body was discovered next to a large supply of nitrous oxide, according to an autopsy report obtained by TMZ Mar. 3. 

The report stated that Bryar’s body was badly decomposed at the time of the discovery and was situated next to three canisters of the chemical compound with tubing attached to them, meaning they were ready for use, per the outlet. 

For reference, nitrous oxide—often called “laughing gas”—is an odorless, flammable gas that can lead to a state of euphoria when inhaled, according to the National Institute of Health (NIH).  

Additionally, the medical examiner said two dogs and antidepressant medication were found in the residence where Bryar passed away, per TMZ. However, officials noted that the decomposition of the musician’s body—parts of which the autopsy described as suffering from “animal scavenging activity”—made it impossible to declare an exact cause of death and ultimately classified it as “undetermined.”
