Four Yale University athletes were killed early Friday when their SUV collided with a jackknifed tractor-trailer on Interstate 95 in Fairfield, Conn.A memorial service for driver Sean Fenton was held Sunday at Yale's Battell Chapel. Fenton, a 20-year-old junior from Newport Beach, Calif., perished along with sophomore Kyle Burnat of Atlanta, sophomore Andrew Dwyer of Florida and sophomore Nicholas G. Grass of Holyoke, Mass. While two students remain in critical condition at Bridgeport Hospital, sophomore Zachary Bradley is listed in stable condition.

The accident took place at 5 a.m., as the nine students were returning from a Delta Kappa Epislon fraternity event in New York.

Grass, who was the fourth student pronounced dead, helped lead the Yale baseball team to the regional finals as a pitcher in 2001.

Fenton, the driver, was remembered fondly as an outgoing athlete and computer whiz. "He was about netowrks, insand messaging, and intramural sports," Yale's Davenport College master Richard Schottenfeld said.

"(Yale) was his home away from home and his friends were his life," Sean's father Robert Fenton said.
