(CNN) The family and friends of Alexis Crawford gathered in Athens, Georgia, on Saturday to honor the memory of the 21-year-old Clark Atlanta University student who police say was killed by her roommate and her roommate's boyfriend.

"This is not going to be about how she died or the evil that took her," said Rev. Markel Hutchins. "Today we're going to celebrate Alexis Crawford's life."

The funeral was originally supposed to be at Hill Chapel Baptist Church in Athens, Crawford's hometown. But the service was moved to Cornerstone Church to accommodate everyone who wanted attend.

Congregants packed the church, shared their memories of Crawford and prayed for her family. The Clark Atlanta University choir sang gospel music.
