Kayla Ferrante was killed a month ago, the night after her high school graduation.
Friends and family lit candles tonight in East Tulsa, to remember Kayla's life.
She had a passion for working with children with disabilities, and planned to spend the summer volunteering at Tulsa's Little Lighthouse.
Ferrante was shot, getting a ride home from a friend.
Her killer hasn't yet been caught.
"I think it's pretty cool how all these people are out here to help support, and it's a big deal to find out who did this so they don't do it again," said a friend of Ferrante's, Paul Perez.
Ferrante's parents have set up a fund to offer a reward for any information about who killed her.
You can call Crime Stoppers with any information.
