A 16-year-old boy was fatally stabbed in Northeast D.C. on Tuesday afternoon, police say.
Tyshon Perry was a student at KIPP DC College Preparatory.
Police were called to the scene near the NoMa-Galludet Metro station about 4:30 p.m. Tuesday. Perry was found unconscious.
He had been stabbed in the chest, D.C. Police Chief Peter Newsham said.
Perry was taken to a hospital in critical condition and pronounced dead, police said.
Police believe the stabbing occurred during a dispute involving a large group of teenagers. They ran before officers arrived in response to several 911 calls.
"We are heartbroken for the parents and family of our student," Susan Schaeffler, the school's founder and CEO, said in a statement. "This is a tragic loss to the KIPP DC College Prep community. We must lean on each other and wrap our arms around our precious children to keep them safe and loved."
