BOERNE, Texas -

A 69-year-old Boerne man was killed Thursday night while riding his bike along the access road of Westbound Interstate 10 in Kendall County.

According to Sgt. Todd Jennings, a DPS trooper at the scene of the crash, the cyclist was struck by an unknown vehicle that fled the scene of the crash that happened around 7:15 p.m. in the 39000 block of I-10 near Boerne.

Jennings said the impact of the crash sent the man into a ditch and left his bike in pieces.

"The bike is one of these race bikes. It's absolutely destroyed. It's a carbon fiber bike and there's nothing left of it," Jennings said.

A passerby who made the initial call to 911 reported it appeared the bike rider had fallen from his bike and was injured.

When officers arrived, they found the man had died from his injuries.

Jennings said there were no witnesses to the hit-and-run, but they are hoping a video surveillance camera in the area may hold some clues.

"We're hoping that one of the businesses behind us here has a camera system in place," Jennings said. "We're working with their IT people to see if we can get access to their video. Hopefully it shows the crash."

Without that video, investigators are going to have a tough time finding the driver who hit the bike rider. Jennings said only one piece of evidence was left at the scene of the crash and it was an antennae believed to be from the vehicle that struck the bike rider.
