A senior at Delta High School could face criminal charges after he threatened a mass shooting, according to a search warrant that was unsealed on Tuesday.

The 17-year-old boy told a female student that he planned to shoot as many people as possible.

The boy also warned the girl to wear a certain color shirt so he would know not to attack her.

That was enough for deputies to get a warrant to search the student’s house and car, where they found a .22 caliber rifle and three cell phones.

The minor student has not been arrested, nor charged with any crime.
