The state attorney’s office for Brevard County announced on Tuesday it is not filing charges against a Melbourne police officer and Florida Tech security guard who fatally shot at a student after he lunged at an officer with a pair of scissors in December.

The family of an 18-year-old Florida Tech University student who police say was shot and killed when he lunged at officers after assaulting people with a knife on campus is speaking out Wednesday morning.

Students at Florida Tech University in Melbourne held a vigil Tuesday night following a deadly officer-involved shooting last Friday.
