SYRACUSE, N.Y. -- Syracuse recruit Omain Gullette, an All-State defensive lineman from Glen Mills, Pa., was shot and killed Saturday afternoon in Philadelphia.

Gullette, 19, was shot 13 times in the chest as he reportedly was trying to mediate a dispute and was pronounced dead at the Hospital of the University of Pennsylvania.

Gullette was headed for Syracuse University on a football scholarship. As a senior at Glen Mills High School, he was a PrepStar All-East Region selection and also was named to the All-Delaware County first team. Gullette was scheduled to play in the Big 33 Classic, an all-star game between players from Ohio and Pennsylvania high schools, on July 20.

"In the recruiting process, we were tremendously impressed about Omain's progress at Glen Mills and his accomplishments not only on the playing field but off," Syracuse coach Paul Pasqualoni said. "The tremendous respect, the teaching, administrative and coaching staffs at Glen Mills had for Omain is what convinced us to recruit him.

"He was a young man with tremendous potential. Our thoughts and wishes are with his family in this time of grief."

Gullette was a state champion in the shot put as a junior and served as student government president.

According to the Philadelphia Daily News, Gullette (6 feet 3 and 310 pounds), known in the neighborhood as "Fats," was hanging out on Glenmore Avenue near 62nd Street in southwest Philadelphia with a friend when three gunmen rounded a corner and opened fire.

More than 30 shell casings were found at the scene, police told the Daily News, fired from an assault rifle, a .45 caliber handgun and a 9 mm semi-automatic weapon.

Police suspect that a previous disagreement was the motive for the killing. Gullette's family could not be reached by the newspaper. There have been no arrests in the case, but police said there were "plenty of leads."

Gullette, at 6 foot 3, 310 pounds, was a physically imposing figure who was also a well-respected leader in school, administrators said.

"He was a big kid, but he had a quiet, laid-back way about him," said Sam Ferrainola, executive director of the Glen Mills School in Concordville, Delaware County, whose student body consists of youths who have been sent there by criminal courts.

Gullette had been arrested four times before coming to Glen Mills, according to the Daily News, but had apparently turned his life around, Ferrainola said. Gullette, who graduated in June, was president of the student government and completed his GED and college preparatory requirements, all while excelling as a football player, shot-putter and discus thrower.
