(CNN) Mourners packed the pews of a Birmingham, Alabama, church Sunday for the funeral of Kamille "Cupcake" McKinney, the girl who was kidnapped from an outdoor birthday party before her body was dumped in a landfill.

Purple and pink flowers and balloons adorned Kamille's tiny casket at the 3-year-old's "homegoing service" at New Beginning Christian Ministry. Colorful cupcakes and an artistic rendering of little Kamille sat alongside the white casket.

The girl's uncle, Steven Long, reminisced about the soft voice she used when she called for "Uncle Steve." Addressing his sister -- Kamille's mother, April Thomas -- and her father, Dominic McKinney, Long said he was only a phone call away if they ever needed to talk.

"Even though it may be sad here for us ... not having her here and needing her here, God has gained an angel in his kingdom," Long told the crowd, which responded with a chorus of amens before breaking into song.

In his eulogy, Pastor Sylvester L. Wilson said he had struggled to come up with a message to share with the congregation. His own granddaughter had just celebrated her third birthday, Wilson said.
