(UNDATED) - Marion County Sheriff John Layton says his "heart goes out" to the family of Deputy Eric Stofer.
Stofer was killed after hitting a pothole on his friend's motorcycle on Indy's southside around 7:30 Sunday evening.
Stofer was not wearing a helmet and Indiana State Police say the bike wound up on top of Stofer.
Sheriff Layton says it doesn't appear that speed or alcohol played a role in the crash, but they're awaiting an autopsy and toxicology results.
Stofer did have a valid motorcycle license, but authorities add he was not wearing a helmet.
Sheriff Layton says while deputies are required to wear helmets on duty, it's up to Hoosiers to determine for themselves whether or not to wear helmets. Indiana does not have a formal helmet law.
The sheriff says it's tough to say which may have played a larger role in Stofer's death, the lack of helmet, pothole or something else.
However, the sheriff adds that he himself hit a couple potholes Monday morning. DPW says crews recently patched potholes in that area.
