An athletic Boston-area high school senior collapsed and died in Greece this week, becoming the third student in his school year to die within six months. Jared Quirk, 18, was in Athens with classmates from Rockland, Massachusetts, to see the ancient world - but fell to the ground while walking through the city with friends, for reasons which are not yet clear. Quirk, who played basketball, baseball, and football at Rockland High School, died a hospital in the Greek capital after being taken there by ambulance, the Boston Globe reported. Sudden death: Jared Quirk, right with his mother and brother, died on Friday in Athens, Greece, while walking with friends. Two others boys who attended Rockland High School with him in Rockland, Massachusetts, also died in the past six months . It was the third day of the trip. Authorities have yet to announce a cause of death for Quirk, whose unexpected passing has plunged Rockland High into mourning for a third time since October. Quirk's death follows that of Joshua Rose, a 17-year-old student at the school, who died suddenly on October 1 for reasons which were not explained in depth. A third contemporary, Patrick Sullivan, 17, was killed in a three-car pileup on New Year's Eve. Other students on the European trip, which was also supposed to take in Italy and last until April 24th, will come home early to grieve. Others: Joshua Rose, left, died on October 1 from an unknown cause, while Patrick Sullivan, right, was killed in a New Year's Eve car crash. Both were 17 and attended Rockland with Quirk .

According to the Enterprise local newspaper, funeral workers and the State Department are working with Greek counterparts to transport Quirk's body back from Athens. An uncle, who asked not to be named, described Quirk as a 'good, sweet kid' to the Globe. According to a neighbor who spoke to the paper, Quirk was considering going to Boston College, where one of his brothers now studies. Marina McCauley, seemingly a classmate, posted a tribute via Twitter. She said: 'Jared Quirk was probably one of the funniest people in our school. I can't believe this.' An online tribute page dedicated to Quirk had amassed 20 entries by Sunday night, mainly from family friends. One, signed Linda Ricciarelli, read: 'My heart is broken for you. My son Ronnie adored Jared. In time I hope your memories will make your heart smile for this wonderful young man that was taken too soon! Thoughts and prayers are with you.'
