Oakland police spokeswoman Johnna Watson said Mr. Nakano, who graduated from the University of Oregon in 2012, was driving back to his Emeryville home after playing basketball with friends at a U.C. Berkeley gym when the collision occurred at about 11 p.m.
He was driving west on Stanford Avenue near Market Street when he was rear-ended by the suspects' car, Ms. Watson said.
Mr. Nakano then "did the right thing" and turned left onto southbound Market Street, pulling over at a bus stop in the 5800 block of Market, near ASA Liquors, she said.
He was then confronted by the two male suspects, and one of them shot him, she said. He was pronounced dead at the scene.
Police don't believe that Mr. Nakano, who would have turned 23 on June 13, knew the suspects prior to the collision, she said.
The suspects' vehicle is described as a newer-model four-door silver sedan.
According to the Register-Guard newspaper in Eugene, Oregon, Mr. Nakano majored in sociology and minored in communications studies at the University of Oregon.
Oakland police and a local Crimestoppers group are offering a reward of up to $10,000 for information leading to an arrest.
Bryan Hickey told the Register-Guard that he played basketball with Mr. Nakano at the University of Oregon Student Recreation Center at least three times a week during their four years as undergraduates together.
Celebration of life
• A celebration of the life of Aya Nakano will be held at 7 p.m. Wednesday, June 19, at the Homer Center on the Sacred Heart Schools campus, 150 Valparaiso Ave. in Atherton.
• Family and friends have established a reward fund with the goal of raising $25,000 in the hope that a witness will step forward with information about the incident.
