Tyler J. Benedict, a band teacher who had worked at the school for 3 years, was arrested on suspicion of first-degree sexual misconduct with a minor on July 31, 2010.

[2] The case began when the victim's parents discovered inappropriate text messages between Benedict and their daughter and reported it to the police.

Her and Benedict both confessed to being in a romantic, sexual relationship and that they committed sex acts on 2 separate occasions within the summer.

Police were called to the scene and originally allowed students to remain in their classes while they swept the school for explosives.

[5] Parents attempting to pick up their children up were asked to wait at a former Albertsons nearby to eliminate any danger of interference or injury.

After a thorough search of the school, the police found nothing suspicious and lifted the lockdown at 4 pm, an hour later than the usual dismissal time.

[6] April 24, 2023, an object resembling a bomb was discovered in the courtyard area of the school and promptly triggered a lockdown.

[8] August 9, 2015, 2 anonymous juveniles were suspected of setting fire to areas of dry grass around the school, causing up to $500 in damages.

[11] The likelihood of the disease spreading was considered low at the time, and no evidence of any other cases were found within the school.

The incident was originally believed to related to the gang violence around the school just a week before, but the Clark County Sheriff's Department (Washington) found no evidence of any connection.

Echevarria was later brought to court on suspicion of first-degree assault and possessing a dangerous weapon on a school campus.

The student was arrested for possession of a dangerous weapon on school property and brought to a juvenile detention center.
