Tucson, Arizona — Editor’s Note: The video above is from a previous broadcast

The semi-truck driver who crashed on Interstate 10, sparked hazmatism across Tucson, and died after shutting down Interstate 10 for more than 24 hours, said the Pima County Medical Inspector. According to the toxicology report, it was under the influence of alcohol.

News 4 Tucson has obtained an autopsy and toxicology report for driver Ricky Immel, who was approved on March 9.

Immel’s blood alcohol level was reportedly four times the legal limit. The upper legal limit was usually 0.08 and Immel’s was 0.312.

Coroner Dr. Gregory Hess said it was at a significant level, but he doesn’t know if it contributed to the crash.

“What we don’t know is his baseline alcohol consumption and tolerance in certain people,” Dr. Hess said.

Dr. Hess pointed out that DPS is investigating the crash and needs to determine if they believe it was the cause.

The Tucson residents we spoke with remembered their fear of the hazardous material all too well and were shocked by the discovery.

Nathaniel Taylor recalled waiting anxiously for the fear that he would have to evacuate his home. He didn’t, but he’s concerned that the whole ordeal may have been caused by drunk driving.

“Honestly, the fact that he’s been on tour for so long is amazing,” he said.

Willie Berian said he was concerned about the fact that the driver was carrying dangerous goods, but was more concerned that things could have been made worse.

“I’m concerned about the fact that he’s transporting dangerous goods, but he’s driving a truck on the highway, if he’s drunk, he’s just driving on the road. I’m also concerned about how many other people I might have killed in ,” he said.

DPS is still investigating the incident and has not commented on the toxicology report.
