Ivan Arturo Aguilar, 21, was riding his bicycle on Kellogg Drive near South Campus Drive on Feb. 28 when he was killed.
University police had been waiting for the completion of a report from the Pomona Police Department's traffic bureau, said Justin Velasco, a university spokesman.
The report found the driver was at fault, Velasco said.
Once the coroner's report is available, university police will file their case with the District Attorney's Office, which will determine whether to charge the driver, Velasco said.
Aguilar was highly regarded among his friends and fellow Cal Poly Pomona students.
The communications major was a member of Hermanos Unidos, a student organization that provides Latino men support as they go from high school or community college to four-year academic institutions. The group emphasizes academics and community service.
News of the police investigation into Aguilar's death comes on the heels of another collision at Kellogg and South Campus on Monday.
Jordan Jarnagin was stuck by a car after 4 p.m.
The lane signals drivers to go straight through the intersection or make a right turn.
Jarnagin planned to go through the intersection.
"The car made a right but didn't have its blinker on," said the 21-year-old Cal Poly mechanical engineering student.
Jarnagin said the impact knocked him onto the car's hood. He said he slid off the car and landed on his back. He suffered a scratch on his left arm and on his back.
He has filed a claim with his insurance provider and is now waiting for the Police Department to complete its report, which should take about 10 days.
"I will peruse getting reimbursement for my bike, but I don't know about pressing charges against the driver because I haven't seen the Police Department report," Jarnagin said.
On Thursday, Jarnagin was at Cal Poly Pomona's traffic-safety forum and Pizza with the President, where students, staff and facility were invited to share their concerns and ideas related to campus safety.
"After Ivan died, more people were shaken up and it became more of a precedence to make things safer on campus," Jarnagin said. "It's sad, but I think it is necessary for something bad to happen for something to be done. "
