Grief counselors were at University Prep Charter School Monday after three teens walking home from school were caught in the crossfire of a fatal shooting Friday.

Angellyh Yambo, 16, was killed, police say. She was heading home when she was struck and killed by a stray bullet near the corner of St. Ann Avenue and East 156th Street.

Another 16-year-old girl and a 17-year-old boy were also caught in the crossfire, but are expected to survive. Those students were also walking home from school at nearby South Bronx Educational Campus.

Police have arrested 17-year-old Jeremiah Ryan in connection with the shooting. He is due back in court and was charged with murder, attempted murder and criminal possession of a gun.

"The community has been rocked by this tragedy. Today is going to be a really tough day for these students and these teachers. I just want to say that I hope that the people with the power to make the tough decisions, make the right ones to make our students safe," says Andrew Ayers, University Prep High School principal.

Parents and teachers are sounding off demanding more safety in schools. School officials are calling for more school safety agents, and implementing a safe corridor program which would supervise students as they go to and from school.

"Senseless shootings of children should never happen on the streets of New York or in a school. If we are not angry about and not upset about it, then we have lost our humanity," says University Prep High School co-founder Randi Weingarten.

Crisis teams and school safety agents were also at the school Monday for students as they grieve.
