CASTLE ROCK, Colo. — A home in Castle Rock has been condemned for safety reasons after suspicious chemicals and explosive materials were discovered inside on Monday, police said at a news conference Tuesday afternoon.
The Douglas County Sheriff’s Office bomb squad was deployed to the home in the Plum Creek neighborhood, and called for the FBI and the Bureau of Alcohol, Tobacco, Firearms and Explosives to bring in specialized equipment.
Investigators found two explosive devices and detonated both at Plum Creek Golf Club as a safety precaution.
Police found the chemicals at the home in the 400 block of Prestwick Way after arresting two juveniles who were out after curfew on Sunday night.
Police went to the home to tell the parents of one of the child’s arrest. While there, police found the small box of chemicals that appeared suspicious and called in hazardous materials crews.
Some of the chemicals were sensitive enough that static electricity could have set them off, said Tommy Barrella with the Douglas County Bomb Squad. The chemicals were purchased legally, Barrella said.
Police said one of the teens had “extensive knowledge” and some of the devices used were illegal. Officials said the devices were never completed but were close to being bombs.
“I have never seen this level of sophistication from a juvenile,” police said.
About 30 homes were evacuated and some spent the night at a Red Cross shelter at the Douglas County Fairgrounds. Residents were able to return at 5 a.m. Tuesday.
Investigators said they have not found any connection between the chemicals and explosives, and Halloween or threats to local schools. Both juveniles are in custody on unknown charges.
Because they are younger than 18 years old, their names, ages and pending charges were not released. Police have not said if the juveniles are boys or girls.
The case has been turned over the District Attorney’s Office for the 18th Judicial District.
District Attorney George Brauchler said he doesn’t believe the juveniles will be charged as adults, but that could change.
Investigators will hold an informational meeting for neighbors affected by the situation at the Plum Creek Golf Course Club House at 7:30 p.m. Tuesday.
