Project Infusion is all about the children, so when tragedy strikes involving young people there was a need to mobilize, Tina Murray, founder of Project Infusion and Osbourn High School instructional assistant, said.
"The idea (for the vigil) came to me Sunday morning, by the grace of God," Murray said.
It was made possible with the support of the Manassas city manager, the mayor and other city officials, she said.
The purpose of the vigil is to bring the community together to heal, she said.
