Those in attendance offered support to the many officers who responded, including Anderson officer Marty Dulworth and Pendleton Police Sergeant Shane Isaacs, who were both wounded when Kenneth Baily opened fire before killing himself.
The community also gathered to show support for the family of Neal Shull, who died in the shooting simply because he was in the wrong place, sitting in his car when the gunfire began.
"We just want you to know, from a community, from me to you, we are there," said Jay Harvey, Pastor at Pendleton Christian Church, to the Shull family. "Whatever it is that you need."
"It's just a tragedy," said Linda Shull, Neal Shull's mother. "You don't think about it happening to your family."
Neal Shull, the owner of a local painting business, was known as a community man who did everything from flip burgers for the Kiwanis club to organizing the town's first car show.
"Just a pillar of the community and everybody knew him," Linda Shull said. "He was very well respected. He was a great husband and father."
Neal's wife was too distraught to speak after the service, but earlier in the day she said she is left asking one question.
"Why? What was the purpose in this man shooting my husband who was only trying to come?" Noelle Shull said. "He wasn't trying to interfere, he wasn't trying to do anything, he was just trying to come home."
There were no answers at the church, but it was clear the healing had begun.
"It brings you closer together and you find out what's really important is family and friends and neighbors and the community," Linda Shull said.
