Prosecutors have not yet announced official charges, but speaking to reporters, the Blue Springs Police Department. Keegan Hughes has raised the possibility of being charged with terrorist threats, which is a felony. Hughes described the suspect as a 19-year-old Blue Springs resident. He was identified with the help of the FBI, Hughes said. Police received a report around 10:30 p.m. on Tuesday for a suspicious post on Snapchat, the statement said, in which someone made a comment threatening “killing people – mass killings”. The man was taken into custody Wednesday morning after overnight surveillance. The threat never mentioned a specific school, Hughes told reporters Wednesday, describing it as “a very general threat.” Police shared the information with the local school district, Hughes said. Although the police did not have a specific possible target, they were aware of the summer planning and the safety of the students was of “paramount importance” to the authorities, he said. In response, Blue Springs School District – which serves more than 14,000 students about 20 miles east of Kansas City – announced on Tuesday that it would cancel Wednesday’s activities “with great care.” The decision was made after Blue Springs police “alerted the FBI to a possible threat of an unspecified mass shooting,” the district said in a statement. He added: “The FBI has confirmed that the person in question, whose whereabouts are unknown, is dangerous.” “We believe that the best course of action is to close the summer school premises and all school planning until further notice,” he said. In statements issued before police announced that a suspect was in custody, some of the districts noted that they had no information indicating that the threat was related to their respective school communities. But, like the Blue Springs, they chose to cancel the activities on Wednesday after great care. The FBI confirmed that it had been informed of the threat by Blue Springs police in a statement to CNN, but asked further questions to this department, which is the main investigative service. “We take all threats of violence seriously and work with our local partners to provide resources as needed,” the FBI said in a statement.
