BOSTON (December 7, 2012)--Boston University graduate student Christopher Weigl, 23, who was killed while riding his bicycle, described the pivotal moment when he decided he wanted to become a photojournalist in an obituary he wrote for himself for a class assignment.

Weigl was on his way to class Thursday when he was struck by a truck.

He wrote his obituary in September and it was reprinted in The Boston Globe.

He wrote that "he cemented his love for photojournalism" during a trip to southeast Asia after graduation from Skidmore College when he did a story about the government takeover of a Cambodian island.

The Southborough native also wrote about his love of music and the outdoors.

His professor in the class called him "the ideal student: smart, mature, curious."
