A prosecutor announced on August 7 that Skamania County will be adding animal cruelty charges against Christopher Wayne Dillingham, 45, a Stevenson, Wash., man accused of attaching an explosive collar to his dog and blowing the animal up, KOMO News reports.
Dillingham was held on $500,000 bail after he appeared in court Monday to face two counts of reckless endangerment and one count of possessing an explosive device for an unlawful purpose.
If convicted, Dillingham could face up to 20 years in prison.
The new animal cruelty charges will be filed at Dillingham's next court appearance, which is reportedly August 15, according to KOMO News.
Dillingham was arrested early Sunday for allegedly detonating the explosive device around 3:45 a.m. outside his home on Loop Road in a semi-rural area on the outskirts of Northwest Stevenson, Undersheriff Dave Cox said.
Several neighbors called 911 to report hearing what sounded like either a high-powered rifle or loud explosion.
The large yellow Labrador retriever’s remains were found on Dillingham's property.
The dog was reportedly a gift from his ex-girlfriend. Dillingham told officers he killed the dog because he believed she had "put the devil in it,” according to the Daily Beast.
He also said he was preparing for “the rapture” as he tossed a couch and other household items onto his lawn after the explosion early Sunday, Deputy Jordan Ejde wrote in an affidavit.
Dillingham owns Thundershack Fireworks, which is just across the Bridge of the Gods from Cascade Locks. He told deputies he made the device from black powder taken from fireworks.
Dillingham reportedly said he distracted the dog with treats as he put the device on the animal.
Cox said investigators believe the device was attached to the large dog’s collar. The undersheriff said the dog died instantly.
Dillingham’s fireworks business has faced state tax warrants for unpaid taxes totally more than $15,500 in all but one of the past eight years, said a Skamania County Court clerk. All but about $5,200 for 2011 and 2013 taxes has been paid, the Oregonian reports.
Investigators from the Bureau of Alcohol Tobacco and Firearms and the Metro Bomb Squad assisted deputies from Skamania County Sheriff's Office and "located several items of evidentiary value," Deputy Cox stated.
