LONG ISLAND, NY -- Four students from the same high school in New York have been found dead within the past month.
On September 13, 16-year-old Nisa Mickens was found beaten to death in Brentwood.
Her close friend, 16-year-old Kayla Cuevas, was found the same way in a backyard, the next day.
Days after that, police found skeletal remains of 19-year-old Oscar Acosta and 15-year-old Miguel Garcia-Moran.
Acosta had been missing since May, and Garcia-Moran disappeared in February.
All four victims had attended Brentwood High School.
A local street gang is suspected, but police did not arrest anyone.
School officials are advising students to not walk alone and to not wear certain colored clothing
