The Prosser School District in conjunction with the Prosser Police Department has been diligently investigating the school threat and recently identified a person of interest. The investigation will continue. We are confident that the individual is not a threat to PHS. Kim Casey, Superintendent

Over the weekend one of our social media accounts received a message of a potential school threat on Tuesday at PHS. This was not a post, but a message, this is why the threat has not been seen on more public forms of social media. We have been working closely with the Prosser Police Department. The Prosser Police Department will have a presence at PHS all day while we continue to investigate the situation and determine the validity of the threat. We will keep everyone informed. The safety of our staff and students is our top priority. Kim Casey, Superintendent
