UPDATE, 6:28 p.m.: Just after 4 p.m., a female student said she saw a man with a gun entering Grantsville High School, according to Lieutenant Watson. That student reportedly ran to tell the football coach on the field, who then called and reported it to authorities.

Officers from several agencies reported to the school, making it there in just a matter of minutes, according to Watson. Since then, Watson said officers have been going through every room in the school — inside and outside. They are also reportedly going through surveillance video.

At this point, officers said they have not seen any person that substantiates the student’s report, however, they said they are going to continue searching the school.

When officers arrived, they reportedly had the few students that were still in the school locked in safe rooms until officers could escort them out.

Watson said the incident has worried a number of students at the school, and that the school will have counselors available tomorrow for those who need it. School is scheduled to resume as usual.

Watson stressed that reports of guns at schools is taken very seriously. Officers are ensuring “no stone is unturned,” according to Watson.
