CASTLE ROCK, Colo. -- Castle Rock Police briefed the media on the latest related to a neighborhood evacuation after deadly chemicals and explosive devices were found in a home there Monday morning.
The 30 or so families ordered to evacuate were allowed to return to the Plum Creek neighborhood Tuesday evening. The home where the chemicals and explosives were found has been condemned.
Authorities say chemicals found inside the home could have caused a deadly explosion if officers had not stumbled upon them. Hazmat crews found more than 20 containers of chemicals inside the house and on the back porch. Investigators had yet to identify the chemicals.
A Douglas County bomb squad detonated two explosive devices behind the home located in the 400 block of West Prestwick Way in Castle Rock.
Castle Rock police say the department arrested two teens Sunday night after neighbors reported they were acting suspiciously, and when officers told the parents of one of the children at their home Monday morning, the officers found a small box of chemicals, prompting the call to hazmat crews with Douglas County.
The two juveniles remain in custody on charges unrelated to the possible explosives. The teens are high school aged. Authorities say one had an extensive knowledge of chemicals. District attorney George Brauchler says prosecutors have not decided whether to charge the teens as adults.
The ATF and FBI are assisting in the investigation. Authorities have not discussed any motives related to case.
The Douglas County Sheriff's Office investigated a possible social media threat earlier Monday, but that threat is not linked to the explosives investigation.
