DENVER (KDVR) — A 42-year-old woman was killed in a crash involving a University of Denver basketball player on Sunday, the Denver Police Department said.

Katharina Rothman has been identified as the victim of a deadly crash that happened just before 2 a.m. at the intersection of South University Boulevard and Buchtel Boulevard. Another person who has not been identified yet was seriously injured, police said.

Coban Porter, 21, was arrested early Sunday morning in connection to the crash, DPD said. He is the younger brother of Denver Nuggets forward Michael Porter Jr. and a DU athlete.

“Lives are lost lives are changed forever as a result of this,” Denver Police Sgt. Mike Farr said.

According to the probable cause statement, Porter was driving at an estimated speed of 50 mph on eastbound Buchtel Boulevard when he ran a red light at South University Boulevard. That is when Porter struck Rothman’s vehicle.

“My friend actually woke up like saying she heard sirens, but I didn’t hear anything or hear about it at all. So it’s really sad,” University of Denver student Sarah Ledous said.

Police said Porter had bloodshot and watery eyes, slurred and mumbling speech and a strong odor of alcohol on his breath. Police also noticed he had a “Bud Light” paper wristband on his wrist.

A blood sample was taken from Porter and the results are pending at this time.
