A man who died last month after being struck by a vehicle while riding a scooter had more than twice the legal limit of alcohol in his system and is responsible for the crash, Metro police have concluded.

Brady Gaulke, 26, received life-threatening injuries after being struck by an SUV at Demonbreun Street and 14th Avenue South on May 16. He died three days later at Vanderbilt University Medical Center.

Police said witnesses watched Gaulke improperly turn left into the roadway from the sidewalk and into the path of a Nissan Pathfinder.

According to a three-page police investigation summary, Gaulke's girlfriend told police she was riding back to her downtown apartment from the Tin Roof on Demonbreun with Gaulke on a separate scooter, and that prior to that Gaulke drank three beers at the bar.

Toxicology reports found Gaulke's blood alcohol content was 0.198% on the night of the crash, the summary states.

"After analyzing the information gathered from the crash scene, speaking to witnesses, and completing the investigation, the proximate cause of this crash was that Brady Gaulke operated a Bird scooter in a reckless manner while under the influence of alcohol," investigator Brian Theriac wrote in a traffic collision report.

The driver of the Nissan Pathfinder was not injured, and no charges will be filed in the case, police spokesman Don Aaron said Friday.

A bicycle lane is present on Demonbreun. Scooter riders are required to follow laws applicable to bicycles being operated on a roadway and are not permitted to be ridden on sidewalks within a business district, according to police.

After his death, Gaulke's family called for the immediate end of scooters in Nashville to prevent more scooter-related deaths.

His parents, Brian and Heidi Gaulke, and younger brother, Dakota Gaulke, asked Mayor David Briley and Metro Council to take action in a Change.org petition launched May 23. So far, their petition has received more than 2,500 signatures.

"He was killed because e-scooters are inherently unsafe in urban environments like

Nashville, on streets filled with fast moving vehicles," the family said in the statement. "We are calling for a ban so Brady is the last victim of an epidemic that the e-scooter companies and local government both refuse to acknowledge.

"We need your help in preventing one more injury, one more death, regardless of fault," they said in the statement.

Nashville Mayor David Briley is exploring a scooter ban and last month gave scooter companies 30 days to resolve safety issues before he urges Metro Council to end their local presence.

The Metro Transportation Licensing Commission is scheduled to release a study on scooter operations next month and the commission will consider new regulations and recommendations for Metro Council at its June 27 meeting, according to commission member Sal Hernandez.

Those considerations could include new fees dedicated to enforcement costs, restricted hours of operations to reduce nighttime riding, requiring helmets or eliminating a two-hour grace period for parking violations.

In April, the commission approved parking corrals for scooters downtown. The first was completed earlier this month.
