Rivas pleaded not guilty Wednesday, the Oregonian reported. Authorities said Rivas struck Portland resident Jean Gerich on Monday and made a U-turn and ran her down again. Gerich died a short time later from her injuries. 

The 77-year-old Gerich was a cancer survivor and was happy to be outside after having received her first COVID-19 vaccination last week, according to a statement from her family. 

Rivas claimed his Honda Element was having brake problems and that he was searching from an auto repair shop when he was spotted driving erratically, according to court documents. He admitted to hitting a cyclist but only as an "emergency maneuver, the newspaper reported. 

Witnesses told the police he appeared to intentionally run down pedestrians and bicyclists. Aside from Gerich, five other people were taken to hospitals with non-critical injuries. After the rampage, Rivas eventually crashed the car and fled on foot, police said.
