The violence erupted after Chris Plaskon, also 16, shoved Maren Sanchez, down the stairs and tried to choke her inside Jonathan Law High School in Milford about 7:15 a.m., friends told the Daily News.
The boy – using a kitchen knife he brought from home – then stabbed Sanchez in the neck, witnesses and cops said.
