John Michael Sturdevant enjoyed spending time at the Howard County Central Library on Little Patuxent Parkway in Columbia.
The 22-year-old Howard Community College student, who was fan of Japanese animation, often went there accompanied by a friend.
But he was walking alone from the library about 5 p.m. Oct. 20 when an eastbound Honda Civic struck him as he attempted to cross Little Patuxent Parkway on the way back to his Harper's Choice home.
He died of his injuries Saturday at Maryland Shock Trauma Center, where he was taken after the accident.
Police said he apparently ran into the road about 75 feet from a marked crosswalk at a traffic signal at South Entrance Road.
His mother, Ann Sturdevant, said he usually used the crosswalk when he walked with his friend, who had warned him against taking shortcuts. She said her son had no vision in his left eye.
John Sturdevant earned his General Educational Development diploma after being home-schooled for high school until age 17, she said. He later enrolled in classes at Howard Community College, where he was studying computer-aided design.
Joey Kasura of Glenwood, a friend who shared an interest in animation, said the two had attended an anime convention in Baltimore this summer.
A Yu-Gi-Oh! club of which Sturdevant was a member held a memorial duel this week in which members played the trading card game with an empty seat in his honor, Kasura said.
"He definitely knew how to make you laugh," said Justin Blacker of Columbia, a friend of Sturdevant from college. "He had a one-liner for almost anything."
His mother said that although he was interested in computer science, her son aspired to be a stay-at-home father.
"He was fantastic with kids," said his mother, who added that he often told her that he wanted to be a "good son."
"But in reality, he was a great son," she said.
The driver of the car, Robert Berkey, 23, of Brookhaven, Pa., was not injured and has not been charged in the accident, police said.
