Confirmed explosive device forces Wildomar school lock down, road closure

WILDOMAR, Calif. — Authorities say the discovery of an explosive device on a Wildomar trail led to the temporary lock down of a local elementary school yesterday morning, Thursday, May 27. The device, described as a pipe bomb, was found in the 32000 block of Wildomar Trail, near the intersection of Illinois Street.

Officials have since said that although the device did contain explosive materials, “the metal on the device appeared weathered” leading bomb squad members to determine that the device had likely been discarded at the location “some time ago.”

Deputies assigned to the Lake Elsinore Sheriff’s Station responded to the scene just before 9 a.m. after a citizen found what appeared to be a pipe bomb on a trail near Wildomar Elementary School, Riverside Sheriff’s Sergeant Collazo has since said of the incident and lock down.

When deputies arrived they located the device and confirmed it appeared to be a pipe bomb.

Deputies evacuated the immediate area and temporarily called for the elementary school to be locked down for safety reasons. They also closed Wildomar Trail to through traffic, diverting motorists and curious onlookers away from the danger zone.

The discovery caused Wildomar’s City Hall to release a social media notification regarding the incident. The post read in-part, “There is police activity near Wildomar Elementary and the school has been placed on lockdown for safety precautions only. There is no immediate threat to the school. We will keep you updated.”

After fielding numerous concerned phone calls, City Hall updated their post to add in-part, “We just want to reiterate that there is no threat to the school or the children/staff. The police activity is outside of the school.”

As the lock down continued into the next hour and Sheriff’s Hazard Device Team (HDT) members and other resources responded to the scene, at around 10 a.m. the elementary school sent out a notification to all parents via text messages and Parent Square that the ongoing investigation was continuing to necessitate the continued lock down of the campus.

Just a short time later, school administrators called for classes to be cancelled for the day, at which time arrangements began for the children already at the school to be picked up. Afternoon classes for children not yet at the school were also cancelled.

According to Collazo, when HDT members arrived they verified the device did in fact contain explosives and rendered the device safe.

Once the device had been detonated and removed from the area and HDT members conducted a safety sweep of the area, officials re-opened Wildomar Trail and lifted the lock down at the school.
