The mourners wept as the three tiny white coffins - adorned by floral sprays of white roses and white carnations - were lowered into the Georgia red clay.
Authorities say the children — 4-year-old Isaac Xavier Guevara Brito; 3-year-old Jose Ivan Guevara Brito; and their younger sister, 18-month-old Stacy Brito Pina — were killed last week when fire swept through a methamphetamine lab in the house.
The children's mother, Neibi Brito, was allowed to attend Wednesday's funeral under heavy guard of Gwinnett County sheriff's deputies, the Daily Citizen of Dalton reported. Authorities are still searching for Ivan Gonzalez, a 26-year-old who has been charged with murder in the children's deaths.
Funeral home director Jimmy Willis said grandparents in Calhoun took responsibility for burying the children, and the family also has ties to Dalton.
Pastor Jose Guevara of Iglesia de Dios Pentecostal church was asked about the words he used in an attempt to comfort the family and friends.
"He said he talked to them about Psalm 23 and tried to give a message of hope," an interpreter related. "He told everyone the children are in heaven now and that we can see them again if we have Jesus in our hearts."
