Three Allentown men looking for a fight brutally attacked and killed a Kutztown University sophomore walking on the borough's busiest street early Friday to get back to his dorm room, authorities said.

Kyle G. Quinn, 19, of Warminster Township, Bucks County, who was in his second week at the school, was beaten at 2:27 a.m. and left lying in a pool of blood on a Main Street sidewalk, about a half-mile from campus.

University President F. Javier Cevallos called Quinn's death "a senseless isolated random act of violence." It stunned the quiet college town and staggered friends and classmates who knew the history major as a gentle soul with a passion for soccer, the outdoors and the martial arts.

Quinn had just left the apartment of his older brother, Dennis, also a Kutztown student, when he was attacked in the 100 block of W. Main Street, a friend said. One of the suspects yelled at the bloodied young man lying on the sidewalk, "Ah, look at you bitch" and "You're a pussy," police said.

Moments later, a Kutztown police officer patrolling the area stopped a car and detained the five men in it. Two brothers -- Terry D. Kline Jr., who turned 22 on Thursday, and Kenneth R. Kline, 21 -- and another passenger, Timothy R. Gearhart, 23, were later charged with aggravated assault and related offenses. They were sent to Berks County Prison under $10 million bail each.

District Attorney Mark C. Baldwin said the three men, who are not students, will probably face homicide charges after an autopsy is done today.

According to the arrest affidavits, Gearhart and the Klines had been drinking at Shorty's Bar at 272 W. Main St., Kutztown. One passenger told police the three harassed others on Main Street before the attack.

At his arraignment, a shackled Terry Kline vomited repeatedly into a bucket. His younger brother, wearing a mohawk cut, smiled and made an obscene gesture to a crowd that gathered at District Judge Wally Scott's courtroom in Reading.

Kyle Quinn, the son of Warminster supervisors Chairman Leo Quinn III, graduated from William Tennent High School in June 2006. He transferred to Kutztown after spending his freshman year studying business at Penn State University's Abington campus. Quinn also had taken a 4-credit biology course at Bucks County Community College over the summer.

His death was Kutztown's first homicide since 1982 and only the third since 1968, officials said.

According to the affidavits:

The Klines and Gearhart, along with Derik Houser and Andrew G. Weber, drove from Allentown to Kutztown and went to Shorty's Bar. Houser told police they left the bar and drove into an alley and onto Noble Street, stopping near Noble and Main.

Houser, 22, said the Klines and Gearhart got out of the car and started causing problems with "a group of kids." Houser said he parked on Main, and he and Weber, also 22, stayed in the car.

Houser said he looked back and saw the Klines and Gearhart with a person he did not know.

Terry Kline was putting his hands up and yelling at this person, Houser said, and later both Klines and Gearhart were yelling at the person. Terry Kline punched Quinn and then he, his brother and Gearhart got back into the car, he said. Houser said he saw the man lying on the ground with blood around his head.

Houser looked in his rear-view mirror and saw a police officer on Main at a traffic light, and Terry Kline told him, "Dee, just leave." Within seconds, Kutztown police Cpl. Paul Clery pulled their car over.

Weber, the front seat passenger, told police he remembered Terry Kline yelling at the person lying on the sidewalk and calling him "bitch" and "pussy."

Quinn had bruises and a deep cut on his head.

Besides aggravated assault, Terry Kline of 1315 W. Tremont St., Kenneth Kline of 930 Oak St., and Gearhart of 124 S. 10th St. are charged with two counts of simple assault and criminal conspiracy and one count of reckless endangerment.
