Driver on learner's permit charged with DUI in crash that killed former Swarthmore professor: DA
UPPER DARBY, Pa. (WPVI) -- An 18-year-old Collingdale man is facing charges after a former Swarthmore College professor was killed while riding his bike in Upper Darby Township, Delaware County.
Police issued an arrest warrant for Kai Poole on Tuesday.
Poole is facing DUI, careless driving, among other charges in the death of 39-year-old Eduard "Teddy" Einstein, the district attorney's office announced.
"It just adds to the sadness and the feeling of loss," said Pat Devlin, a professor at Swarthmore College.
According to police, Einstein was struck by a car Poole was driving near West Providence Road and East Penn Pines Boulevard in December 2025.
Officials say Poole, who only had a learner's permit at the time of the crash, was allegedly driving the vehicle alone, while under the influence of marijuana.
"It's very clear that the individual driving was under the influence of marijuana and this was an accident that could have been prevented," said Delaware County District Attorney Tanner Rouse.
Investigators say Poole did not properly yield while making a left turn, striking Einstein.
Einstein was in the bike lane with all his safety gear on when he was struck, police say.
Einstein's loved ones have since pushed for safety improvements along the stretch of Providence Road where the crash happened. They say PennDOT has committed to installing trafficcalming measures.
"Using paint and plastic post, hopefully making the improvements will see them this summer," said Jacob Russell, also a professor at Swarthmore College.
Colleagues remember Einstein for not only his intellect, but heart.
"He was really excited to do home improvement projects. He was a dedicated father. He was a loving guy. He will be missed by family but also friends," Devlin.
Friends say they are in the process of publishing one of Einstein's final works and plan to hold a celebration of life next month.
Einstein leaves behind a wife and two young children.
