STATE COLLEGE, Pa. (AP) — A Pennsylvania prosecutor says no charges will be filed in the death of an autistic man shot by police earlier this year.

Centre County District Attorney Bernie Cantorna announced Wednesday that a State College officer was justified in shooting 29-year-old Osaze Osagie, who officials say was armed with a knife and confronted three officers trying to serve a mental health warrant March 20.

Cantorna said in a 228-page report that officers “acted consistent with their training” and were in a “life or death situation.” State police said race played no role in the shooting of Osagie, who was black.

Osagie’s parents said in a statement that the decision “opens a new wound” and they “will forever regret reaching out to the police to seek emergency help for their son.”

Students at Penn State University and members of the State College community have organized around the hashtag #WeAreNot to protest not only Osagie’s fatal shooting but police brutality and systemic racism as a whole.

“We are not here to be pacified or negotiated with,” Gabriel Green, a doctoral student at Penn State and a spokesperson for the group, told HuffPost. “Justice was demanded. Justice was denied. Therefore, the protests will continue indefinitely.”
