High school students raise more than $260,000 for elderly custodian so he can retire

Three high school seniors from Callisburg, Texas, learned that an 80-year-old janitor at their school didn't have enough money to retire, so they decided to help him out. 

The trio — Greyson Thurman, Marti Yousko and Banner Tidwell — from Callisburg High School launched a GoFundMe campaign on February 15 that generated more than 8,000 donations totaling about $260,000. Most of the donations came from Callisburg students and staff, the students said. 

"It's amazing," Callisburg High Principal Jason Hooper told CBS affiliate KXII. "The need that was met because of three kind kids — of all of our students who pitched in to meet that need," he said.
