The grandson of Duke University’s legendary Mike Krzyzewski is facing a DWI charge after a fatal collision with an e-bike, according to a report. ​

Joseph Savarino, the 26-year-old grandson of the man known widely as Coach K, allegedly hit the 15-year-old cyclist in Durham, North Carolina, on Saturday.

The teenager was struck at around 9 pm by a Ford Explorer and died at the scene, the Durham Police Department told WRAL.

The victim was identified by his mother on Facebook as Jack O’Shea.

According to public records, a breathalyzer test showed Savarino’s blood-alcohol concentration was at 0.11 percent. The legal limit in the state is 0.08 percent. ​

Savarino also admitted to authorities that he drank alcohol earlier that evening, police said. He was held on a $100,000 secure bond at a local jail.

The bond was eventually posted by the suspect’s mother, Debbie Savarino.

Now, the suspect is facing a misdemeanor charge of driving while impaired, according to records. A judge has also issued an order to revoke Savarino’s driver’s license. ​

Jack O’Shea was identified as the boy killed in the collision by his mother, Allison, on social media. ​

“He woke up and asked to go to confession at Immaculate Conception Church,” Allison wrote. “He then played two baseball games with his high school team, where he did what he always did — showed up fully and excelled at first base.​

“Later, he went on his usual afternoon bike ride with friends,” she continued. “As he was coming back into our neighborhood, he was involved in an accident and was hit by a car.​

“Jesus took him immediately.”​

Savarino’s grandfather, Mike Krzyzewski, served as the head coach at Duke University from 1980 until 2022. During his tenure, he led the Duke Blue Devils men’s basketball team to five national titles and won more than 1,202 games, according to the university’s website.

​Krzyzewski also led the U.S. men’s basketball team to gold medals at the 2008, 2012 and 2016 Olympic Games. ​

Savarino’s mother, Debbie, is Krzyzewski’s daughter. Her other son, Michael, was convicted on a DWI charge in 2022 and sentenced to 12 months of probation, according to court documents viewed by WRAL.

Michael, who was a walk-on for his grandfather, had been arrested in Orange County in 2021 while driving his teammate, Paolo Banchero’s, car.

Banchero was charged with aiding and abetting DWI, but the charges were eventually dropped, according to ESPN.

The Independent has contacted Butch Williams, Savarino’s attorney, for comment.
