LAS VEGAS (KLAS) — A former Desert Oasis High School student who planned an attack on the school entered a guilty plea on Nov. 20, according to online records. After the plea was entered, 18-year-old Cody Pomeroy’s sentencing was set for January 8, 2020.
An arrest report obtained in August said he planned to use a mortar rigged with glass jars for shrapnel.
Pomeroy was charged with making a terroristic threat and “possession of component of explosive or incendiary device with the intent to manufacture explosive of incendiary device” in August. A witness said the attack was revenge on a person that was “speaking badly” about his group.
At least one other person was involved in the plot, according to the arrest report from the Las Vegas Metropolitan Police Department. Police learned of the plan from an assistant manager at the McDonalds at Rainbow Boulevard and Blue Diamond Road where Pomeroy worked.
The names of other were redacted in the arrest report.
The device recovered by the Metro bomb squad was described as a “mortar stacking.” Heavy glass jars were affixed to explosives and a commercial fuse was used.
Pomeroy admitted he built the device on July 5 after he was playing around with fireworks, police said. He had planned to set it off in the desert. He said he knew that the glass would break and shatter.
Pomeroy talked about the planned attack while at work, and the threat — initially dismissed — was originally to attack on Monday, Aug. 19. Someone involved in the plot was sick that day, Pomeroy told his assistant manager.
When Pomeroy set a date for the attack, he told the assistant manager, “It’s all set, waiting for the time!”
Managers at the McDonalds contacted police.
One person told police they believed Pomeroy was suicidal.
Pomeroy said that he and others involved were going to wear white, and that would be the signal that the shooting would happen.
Pomeroy was taken into custody in August after law enforcement became aware of his alleged threat.
