A 20-year-old suspect is facing voluntary manslaughter charges after fatally assaulting a grandfather and recent retiree who was enjoying his cup of coffee at a Starbucks in Rocklin, California.

The alleged victim, Robert Ketner, 69, died in the hospital as a result of his injuries from the confrontation that violently escalated.

Police identified 20-year-old River Baumann as the suspect who allegedly punched the grandfather after being told to turn down his loud music.

Ketner fell to the ground after the attack and sustained an injury to his head that led him to lose consciousness.

A family member of Ketner – who wished to remain anonymous – told KTXL:

“He was kind of sitting outside, drinking his latte when the vehicle of some sort came by.”

“It was like really loud music; people were complaining about it. So, he pointed out, like, which car it was and asked them to turn their music down.”

Police arrived on the scene after the attack and discovered the victim was unresponsive. They took Ketner to the hospital, but he never regained consciousness.

Rocklin Police Cpl. Zack Lewis said:

“Whatever the argument was, no one deserves to lose their life.”

“So, it’s a sad thing that we have to experience this.”


On Sunday night, officers arrested Baumann on a battery charge in connection to the Starbucks altercation and later bailed out.

When the alleged victim died, the suspect was rearrested on Wednesday and now faces a manslaughter charge.
