With his back turned to his two friends, he couldn’t have seen it coming.

Sunday morning at approximately 2 a.m., three students were walking back from a party near Columbus Avenue. When they crossed Tremont and Northampton Streets, two of them were hit by a turquoise Mercury Tracer sedan with a yellow pinstripe on it, said Mariellen Burns, Boston Police public relations director, during a press conference Sunday.

Gena Prastos, a freshman communications major, and Fergal Edward Brady, a business exchange student from Dublin City University in Ireland, were the two victims involved in the early morning hit and run.

“I was walking about three feet in front of them,” said the third friend walking back early Sunday morning. “I had my back turned and then I turned around and saw them on the ground. I didn’t know what to think, I was in disbelief.”

As of last night, Brady, who came to Northeastern in January, was in critical condition at Boston Medical Center with severe head trauma.

Prastos was treated and released from Brigham and Women’s Hospital Sunday afternoon, but was brought back by her parents a few hours later after she felt dizzy and nauseous. Prastos was again released Monday afternoon.

Marcy Prastos, Gena’s mother, flew to Boston with her husband to be with her daughter and is now focused on helping her daughter recover.

“She’s lucky to be alive,” Marcy said. “Now I’m focused on getting her healed and making sure she will be able to get back into her schedule as easily as possible.”

Prastos said she has at least three staples in her head, bruises all over her body and is on medication for pain.

“I have staples in the back of my head, my leg is killing me, I think I pulled some ligaments, bruises all over my body, and I am just really sore. I’ll get over it though, I’m the lucky one,” Prastos said.

Just before Prastos started to tell her story, her mother’s cell phone rang and on the other line was President Richard Freeland. Prastos’ mother said he wanted to see how her daughter was doing.

“The university has been so great,” Marcy said. “The school has been really supportful, and I appreciate all the help.”

Dean Ira Weiss of the College of Business Administration, where Brady is a student, called the incident a “tragedy” and hopes both students will recover in the near future.

“It’s a terrible tragedy that two students got hit in a hit and run. I am very, very hopeful that the students will be on the road to recovery very soon,” Weiss said.

Prastos’ room contains the multiple flower arrangements brought to her by concerned friends. Prastos said she has been living on soup and crackers, but her friends have brought her cake, ice cream and even sushi.

Prastos said while she is doing alright, she will feel better when she finds out about Brady.

“I will be more comfortable as soon as my friend wakes up,” Prastos said.

Prastos’ mother said her daughter might need physical therapy for her neck, shoulders, back and knee, but they will not know for sure for a couple of days. The 18-year-old victim will not return to classes until she can function without pain.

Prastos is waiting to see what she will have to do about completing her spring semester and is planning on interning at YM Magazine in New York over the summer.

Witnesses described the driver of the Mercury Tracer as a black male in his 40’s. Boston Police are still searching for the car and suspect and encourage anyone with any information to contact District 4 Detectives at 617-343-4250 or 1-800-494-TIPS.
