An 18-year-old woman died after a two-car crash Friday afternoon on American Legion Highway in Roslindale.

Police would not identify the victim. But students at the Boston Community Leadership Academy in Hyde Park said she was a senior at the school, where officials offered grief counseling for her classmates Saturday.

Boston Public School officials confirmed only that a student at the school died Friday, but declined to identify the woman.

Officer Stephen McNulty, a Boston police spokesman, said the crash is still being investigated.

McNulty said five other people suffered injuries that were not life-threatening. He said it appears that three passengers were in each of the cars involved in the crash.

One vehicle was flipped over after the collision, which occurred at the intersection of American Legion Highway and Clare Avenue, according Boston EMS Lieutenant Scott Beers.

Beers said at least two people were taken to Brigham and Women’s Faulkner Hospital and Boston Children’s Hospital.

The leadership academy is in the Hyde Park Educational Complex, along with the New Mission High School.

According to state enrollment figures, the academy has 525 students, while 319 attend New Mission. Students from the two schools associate with each other, and students from both schools were offered grief counseling Saturday.

On Friday afternoon, Boston school Superintendent Tommy Chang announced that a student from the academy died off-campus that afternoon.

“Our thoughts and prayers are with BCLA and New Mission High School community,’’ he said.

Anthony Pope, the district’s instructional superintendent for high schools, said grief counselors were assigned to the school Saturday morning. About 50 students came to the building, he said.

Pope said additional support will be available when students return for classes Monday, and there will be meetings for staff to help them prepare to assist students as well as each other. A pastor from a faith-based organization will also be on hand, he said.

“We’ll make sure every student and staff will have the support they need,’’ Pope said.

On Saturday morning, groups of students clustered around each other, giving hugs and whispering words of condolence.

More than a dozen students could be seen gathered around a locker, where a bouquet of flowers was attached to a door along with a card with a heart drawn on it.

Classmates of the student who died Friday described a quiet, sweet person who planned to attend college after graduating this year.

“She was a sweetheart,’’ said Lisandra Francisco, a New Mission student as she walked along the sidewalk outside the building.

Mataya Young, who attends New Mission, said this is the second classmate they’ve lost this year, saying a student died in August. Outside the school building Saturday, a weathered memorial by the front doors was dedicated to the student who died last summer.

“Something good has to come our way, “ said Young. “It’s too much.’’

Daniel O’Brien, a spokesman for the School Department, confirmed a New Mission student died of a medical condition in August, but did not have further information.
