Debbie Bolf said she's just about cried her eyes out.

Her best friend, Karla Holcombe, along with seven members of Holcombe's family were killed in the mass shooting Sunday at the First Baptist Church of Sutherland Springs. They are among the 26 dead and at least 20 injured in deadliest shooting in Texas history.

"When I heard the news, I called Karla right away. The phone kept ringing, and I knew she was dead, and I cried. She was a best friend," said Bolf, who is the executive director of All City Youth Programs in Floresville and has known the Holcombe family for more than 30 years.

Karla's husband, Bryan, who owned American Canvas Works in Floresville, was also killed. Of their four children, one son, Danny, is dead, along with his 18-month-old child. John Holcombe was shot in the leg, and his pregnant wife, Crystal, was killed. Three of John and Crystal's five children were also killed.

Bryan and Karla's two other children, Sarah and Scott, are OK, Bolf said.

Bolf said Bryan donated the old American Canvas Works building to a church next door called Harvest Christian.

"They were very giving Christians, and they believed in being good neighbors," Bolf said. "They loved working in the church and helping others."
