BROOKLYN - Neighbors say the 17-year-old Coney Island girl who died this week after being attacked outside her home Friday could have been saved.

Police have accused Sarina Agard-Forde, 18, of beating Ta'Jae Warner on April 1 until she lost consciousness. Warner died two days later in a hospital.

But neighbors in her building say that with so many people living there, someone should have stepped in to stop the attack.

They accuse the building's security of spectating instead of intervening.

Agard-Forde was arrested on charges of assault and attempted assault, but a grand jury could decide to upgrade those charges.

It's unclear whether there were more people involved in the assault.

Warner's family declined a News 12 request for an interview. Friends say they just want time to grieve.
