A man has been charged with driving under the influence after police said he hit a man on a scooter and then ran away from the scene in Montgomery County late Saturday night.

Employees at Bethesda’s Oakville Grille & Wine Bar were remembering 56-year-old Ross Redler Sunday as a beloved colleague and talented pianist.

Around 11:15 p.m., police responded to the intersection of Rockville Pike and Congressional Lane for a report of a collision.

Police said Redler was in a 2014 Tao Tao scooter traveling southbound on Rockville Pike.

Mark Andrade, 24, was attempting to make a left turn from Rockville Pike onto Congressional Lane, in the opposite direction.

Police are still investigating the cause of the accident.

After the collision, police said Andrade stopped his vehicle and fled on foot.

Redler was transported to a nearby hospital where he died from his injuries.

Officers located Andrade and arrested him for driving under the influence.

Andrade was not injured in the crash.

Margaret Dempsey, who worked with Redler at the restaurant, said she and her colleagues are still in shock.

“It’s not even real,” she said.

Dempsey works as a bartender at the restaurant and said the staff worked together like a family.

On the first day of Hanukah, Dempsey said Redler invited all of his coworkers to a prayer service.

"He lit the candles and he said a Jewish prayer. It was very lovely,” she said.

"He helped whenever he could help. He did whatever he could do for anyone. Very sweet person. A very talented musician. A pianist."

"There's no reason not to call a Taxi or some other way of getting home,” she added.

On Maryland Case Search, WUSA 9 found Andrade had a recent history of traffic violations, including two for hitting excessive speeds.

Redler’s colleagues said he had left for home earlier on Saturday.

Dempsey was not sure if Redler had stopped to run an errand, but said he was near his home.

According to his Facebook page, Redler lived in Rockville and attended Bethesda-Chevy Chase High School.

WUSA 9 reached out to Andrade’s family, but they declined to give a statement due to the ongoing investigation.

Police plan to consult with the Montgomery County State’s Attorney’s Office to determine whether Andrade will face additional charges related to the crash.
