Photo by Liz Copan / Summit Daily archives Summit County Judge Edward Casias ruled that employees of the Colorado Avalanche Information Center would be required to testify in the trial of Evan Hannibal and Tyler DeWitt next week, dismissing a motion from the Colorado Attorney General’s Office to quash their subpoenas and keep them off the witness stand. On March 25, DeWitt of Lakewood and Hannibal of Vail were snowboarding above the Loop Road at the Eisenhower/Johnson Memorial Tunnels when they triggered an avalanche. Nobody was injured in the slide, but it covered more than 400 feet of the active roadway below in debris up to 20 feet deep and damaged a remote avalanche-control unit.
