The Family Of Michael Hill, A Custodian Who Was Killed In A Shooting At The Nashville School, Asked For "Compassion For One Another"

Michael Hill, the longtime custodian who was killed in a shooting at the Covenant School in Nashville, would have wanted people to show compassion to each other, his family said.

"I think it's a normal thing to be upset and frustrated and angry. But those are the things that slowly eat you up over time," his son Joshua Smith told NBC News Thursday.

"I believe our dad would want us to show compassion, compassion to one another, and to any family that's been affected by the tragedy," Smith said.

Hill, 61, was one of six people killed when a shooter opened fire on the school on Monday. The other victims were substitute teacher Cynthia Peak, 61; head of the school Katherine Koonce, 60; and 9-year-old students Evelyn Dieckhaus, Hallie Scruggs, and William Kinney.

Smith said his dad would have been crushed had he known that some of the victims were children.

Known as "Big Mike" to the kids in school, Hill was a beloved staff member who had worked at the Covenant School for 15 years.
