In 1990 a guy from boulder went up to left hand canyon. I believe he killed 2 and wounded 3 more. They looked for him for 3 days. If I remember right he said he was with the forest service and wanted to check there guns. They did arrest him.

Shooting rampage


Prison officials later admitted it was a "mistake" to leave Michael G. Bell in a minimum-security prison. If they had realized that before Bell escaped on Aug. 5, 1990, what is believed to be the most violent shooting rampage in Boulder County history might never have taken place.
Eleven days after his escape, Bell robbed a Circle K in Broomfield, murdering night clerk William Brian Lewis, 18, in the process. Five days later, Bell shot and killed Leslie Ross Thomas, 36, in Boulder Canyon.
Then, on Aug. 24, Bell, posing as a park ranger in Lefthand Canyon, asked a group of target shooters to turn over their guns. They did, and Bell opened fire on them, killing Jim Dockus, 20, and Christopher Schilling, 21. Three others were wounded.
More than 100 officers fanned out in the biggest manhunt ever in the county. The day of the Lefthand Canyon shootings, Bell was arrested by a sheriff's deputy.
He was charged with 20 counts in the rampage. The death penalty was considered, but it was decided to let Bell plead guilty to the murders and attempted murders. He was sentenced to life in prison without parole for each murder, and 48 years for each attempted murder. He was the first person to be given life without parole under a law enacted in July 1990.
The investigation, arrest and trial of Bell garnered a great deal of media interest - the most in recent years until the Ramsey case, Epp said. Epp described the biggest difference between the media coverage of the Bell case and the current media circus surrounding the Ramsey case. "It was all local media - we didn't have anyone from out of town," said Epp. "And they were helpful."
