Scott Lee Kimball is born at Boulder Community Hospital to Virgil and Barb Kimball.

He would grow up in Old Town Lafayette, attending Lafayette Elementary and Lafayette Middle schools.

“He wasn’t one of the popular kids,” said Tina Goeden, 42, who went to elementary school with Kimball. “He was pretty quiet.”

But police knew early on that Scott Kimball could be trouble.

Lafayette police Cmdr. Mark Battersby remembers responding to a call involving the adolescent Kimball within a few years of joining the force in 1976.

The boy had gotten a hold of one of his father’s guns and was shooting out of his home, hitting other houses, Battersby said.

“I knew he was going to be a handful.”

Kimball also attended Centaurus High School in 1981, but withdrew after one month and moved to Montana.
