Hundreds of runners took to the streets of Andover, Massachusetts, on Sunday to celebrate the life of Colleen Ritzer.
The annual Step Up For Colleen 5K began after the Danvers High School teacher was raped and killed by her then student- Phillip Chism.
Chism was sentenced to life in prison last December.
Family and friends remember the impact Ritzer had on the community by raising money for scholarships for teens who want to pursue careers in teaching.
