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.

At the start of his freshman year, Scott Kimball moves to Hamilton, Mont., to live with his father and younger brother, Brett.

He attends Hamilton High School, in the town of 4,000 people an hour south of Missoula, but drops out as a senior.

Nearly a year after Terry Kimball’s disappearance, Scott Kimball’s father, Virgil Kimball, receives an e-mail at his Idaho home from terrylkimball@yahoo.com.

“In the e-mail, Terry claimed to be living in old Mexico with a woman named Ginger and added that Ginger liked living in Mexico,” FBI agent Johnny Grusing would later write in an affidavit. “Virgil recalled that supposedly Ginger never wanted to return to the United States, so Terry probably would not either.”

Police would trace the account to Scott Kimball’s computer two years later.
