Bellevue police recognized a Bellevue High School student on Friday for his heroic efforts on the side of a California freeway in 2016.

According to a news release, on Aug. 16, 2016, then-13 year-old Daniel Tyshler was riding in a vehicle on the Interstate 405 freeway in southern California with his 11 year-old brother Jonathan and their grandparents. Daniel and his brother were on vacation.

Suddenly, and without warning, Daniel’s grandfather suffered a heart attack while driving. The car veered across five lanes of traffic, narrowly missed a guardrail, and came to a stop in a grove of trees on the side of the freeway.

Daniel and his brother quickly went into action. Daniel immediately called 911, and then coached his frantic grandmother on how to turn off the engine and unlock the doors of the vehicle. Then, with the help of a citizen who had stopped, Daniel and Jonathan removed his unconscious grandfather from the vehicle and immediately began administering lifesaving CPR until first responders arrived at the scene. Responders were able to locate a pulse, and Daniel’s grandfather was transported to the hospital and made a full recovery.

During a student assembly at Bellevue High School Friday, Bellevue police school resource officer Jeff Borsheim presented Daniel a certificate of recognition from the California Highway Patrol for performing life-saving medical aid.

In the award, California Highway Patrol Capt. Ryan Shackleford acknowledged Daniel’s bravery.

“You are being commended for your swift action, calm demeanor, and poise under pressure while saving a life,” Shackleford wrote. “It takes a very special kind of person to act in the face of adversity, congratulations.”
