According to a statement from the Lyon County Sheriff's Office, the substance found was a muriatic acid which was to be mixed with aluminum foil to create a works bomb that would create a binary non-flammable explosion when mixed.
Three students were questioned and admitted to possession of the substances, but maintained that they were not going to create the reaction on school grounds. The school was placed on lockdown for approximately 45 minutes while deputies searched for additional materials. At the conclusion of the search, the lockdown was lifted and a montiored release of the students was conducted, according to the Lyon County Sheriff's Office.
An investigation is still ongoing and anyone with information is asked to contact Sgt. Bryan Parsons at 775-463-6620.
DAYTON, Nev. (KRNV & MyNews4.com) -- Students at Dayton Intermediate School were held in class due to an unidentified liquid.
According to Keith Savage, the Lyon County School District Superintendent, the liquid was in a student's water bottle and was reported before 2pm.
Administration called Lyon County Sheriff’s Office to investigate and school officials held students in class for about 30 minutes to make sure there was no threat.
Students were eventually let go by school administration and boarded their buses late once it was determined that it was safe to release students.
Sheriff deputies are still investigating to find out what the liquid is.
The principal will be contacting parents of students tonight to discuss the situation.
Savage says school will be open tomorrow for students.
