A Boulder elementary school was on secure status Tuesday as deputies investigated reports of shots fired in the area, sheriff’s officials said. Investigators believe the sound of reported gunshots was actually a squirrel tripping an electrical fuse, Boulder County sheriff’s officials said after talking to Xcel Energy. As of 12:15 p.m., Douglass Elementary School in Boulder had been given the all-clear after a building-wide search, Boulder Valley School District officials said in an alert. The loud cracks previously believed to be gunshots were heard around 11:30 a.m. Tuesday near North 75th Street and Baseline Road, just down the street from Douglass, according to the Boulder County Sheriff’s Office. Sheriff’s officials said the school was put on secure status while deputies investigated and all of the students are safe. When a school is on secure status, all doors are locked and no one may enter or leave the building, according to school district officials. Students involved in outside activities are brought indoors but classes continue as normal. This is a developing story and will be updated.  Related Articles Crime and Public Safety | Man sentenced to 3 years prison in Crown Hill Cemetery crypt robbery Crime and Public Safety | Arvada pays $2 million to settle lawsuit after police officer killed pregnant woman Crime and Public Safety | Colorado’s backlog to test rape kits now tops 500 days, rising in fallout of scandal involving DNA scientist Crime and Public Safety | Edge of Lowry apartments in Aurora to close in February, court case ongoing Crime and Public Safety | After deadly 16th Street Mall stabbing spree, mayor defends downtown Denver safety Sign up to get crime news sent straight to your inbox each day.
