A 12-year-old-boy fatally injured by a van in Allston this morning has been identified as a seventh-grader who attended a Catholic school in Roxbury.

Barrington Brinson went to St. Patrick School, which is located on Mount Pleasant Street. In a letter sent to parents, Principal Mary Lanata wrote that the child’s death had shocked their community.

“Speaking on behalf of the St. Patrick School community, I want to express our deep sadness over Barry’s death. Our Christian faith teaches us that our life on earth merely prepares us for an everlasting life with God who sent His son, Jesus, to obtain this for us,’’ Lanata wrote in the letter. “Of course, we are deeply troubled when a young man leaves our company far earlier than any of us expected.”

Lanata said that Brinson had a sibling, a brother, and she urged members of the school’s community to remember the family.

“We grieve for Barry’s parents and brother who must bear this loss and the suffering that comes from his departure. I ask you to pray for Barry and for his family, that they may receive the consolation that will come from trust in God our Father and his everlasting love for us all,” she wrote.

Brinson was an honor roll student who played basketball, sang in the spring music concert, and served as a tech for the Easter Passion play. He had attended the school since kindergarten, said the Rev. Walter Waldron.

Brinson suffered a head injury when he was struck outside 460 Cambridge St. near the entrance to a Walgreens store just before 6:50 a.m., according to Boston police and Boston Emergency Medical Services.

The name of a Holyoke company, Aegis Energy Services, was visible on the side of the white van. In a brief telephone conversation, a woman who answered the phone at the company’s office said they were waiting to get more information before commenting.

“Out of respect for the seriousness of this incident, we are reserving the right to comment until we have more information on the situation,’’ said the woman, who declined to identify herself by name.

The incident took place near the firehouse for Engine 41 and Ladder 15. Boston Fire Department spokesman Steve MacDonald said firefighters rushed out and provided emergency medical assistance until ambulance crews arrived.

Brinson was transported to nearby St. Elizabeth’s Medical Center in Brighton, where he succumbed to his injuries, authorities said.

Police shut down Cambridge Street this morning while they investigated. They left the vehicle parked on Cambridge Street as they plotted the locations of evidence in the fatal crash. Until police picked it up, the backpack was visible as it lay next to the left front bumper of the van.
