Rocklin Starbucks employees temporarily closed the store on Thursday after learning of their customer’s death.

“I just can’t believe it,” Starbucks customer Beverly Pilcher said.

Rocklin police arrested 20-year-old River Baumann on voluntary manslaughter charges in connection with the death. They say Baumann was in a truck at the Starbucks and the pair first got into a verbal argument that quickly escalated.

“The victim was punched and he fell to the ground sustaining an injury to his head and he never regained consciousness,” Rocklin Detective Zack Lewis said.

Baumann’s mugshot shows a rose tattoo on the side of his face. Police say that wasn’t the only description they used to arrest him.

“He was identified by other means, not just his tattoo so, there’s people that knew his name,” Detective Lewis said.

After initially being arrested for the attack on Sunday, Baumann bailed out of jail. Police re-arrested him on a new voluntary manslaughter charge after his alleged victim died in the hospital.
