A graduate student from the International Business School was arrested May 7 for drunk driving and hitting three students on a Waltham sidewalk, police said. The students sustained only minor injuries. Solon Magrizos, 24, was booked by Waltham police about 2:30 a.m. after he drove his car across the opposing lane of traffic and onto the opposite sidewalk at 156 South Street, the police report said.

Magrizos was on his way home to 110 Angleside Road from a party on Dartmouth Street when he lost control of the car.

"I'm sorry, I was drinking and should not have been driving," he told officers, according to the police report. "It's all my fault,"

Magrizos faces charges of operating under the influence, negligent operation, driving left of center and not having a Massachusetts driver's license, Detective Sergeant Tim King said.

Magrizos was arraigned May 8, pleaded "not guilty" and was released on his own recognizance. He appeared with counsel May 15 at Waltham District court, where he was ordered to surrender his passport as a term of release.

Magrizos is due back in court May 31 for a pre-trial conference. A trial date has not been set.

He declined comment under legal advice. John Pavlos, Magrizos' lawyer, did not respond to multiple phone messages.

The injured students, Leah Edelman '08, John Guilinger '08 and Emily Terrin '08, were treated for minor injuries at Beth Israel Deaconess Medical Center, according to court documents. American Medical Response Ambulance personnel assisted the victims on scene.

Terrin, whose injuries included neck, chest and leg pains, said she lost consciousness and did not remember anything after being struck by the car.

Rebecca Kupchan '09, who witnessed the accident, remembers differently. She said none of the injured students lost consciousness, and each was able to speak with officers minutes after they arrived.

Terrin said Magrizos hit them from behind while they were walking back to campus from a party on Dartmouth Street. The police report didn't say whether they were coming from the same party.

Edelman declined to comment and Guilinger could not be reached for comment.

Kupchan said the three students were walking around 50 feet ahead of her when "out of nowhere," Magrizos' car swerved across the road and onto the sidewalk. One of the females hit flew across the windshield, Kupchan said.

Witnesses told officers no other cars were on the road at the time.

"From the distance I saw that there were bodies on the ground, but I couldn't comprehend that fast what happened," Kupchan said.

Mark Edwards '09, who was walking with Kupchan, ran ahead to check on the victims and asked someone in a house on the corner to call the police.

"It felt like 30 seconds," Kupchan said of waiting for the police to arrive. "Within a minute for sure we were surrounded by police cars and ambulances, and they had blocked off the street."

Officer Stephen Clarke, who filed the police report, said Magrizos appeared highly intoxicated and could not balance himself.

Magrizos told officers he is licensed to drive in his home country, Greece, though he could not locate the license in his 1992 Buick La Sabre.

Carlos Perez de los Cobos (GRAD), also an IBS student, was a passenger in the car. Perez told officers he and Magrizos had been to a party in Mod 10.

Students from Mod 10 refused to comment on Magrizos' state that night.

Magrizos told officers he had several shots and drinks that night, starting at 11 p.m.

Magrizos was placed in a holding cell at the Waltham police station and released at 11 a.m. that morning. His vehicle was impounded for 12 hours at White's Garage in Waltham.

Since that night, Kupchan said neither the court nor the police have contacted her.
