INDIANAPOLIS, Ind. (Dec.17, 2015) – Multiple schools were placed on lockdown or closed Thursday because of threats made.

One threat was made directly to students at Plainfield High School. In that case, someone posted on Facebook detailing a specific target in a disturbing and graphic manner. FOX59 has chosen not to show the posts made by the suspect.

Indiana State Police is not involved in the investigation, but cyber crimes investigators are weighing in. ISP Captain Chuck Cohen said investigators will first look into identifying where the suspect is located. They’ll also work to identify the suspect and determine if the threat is legitimate.

“Sometimes attributing identity, tracing a particular threat can be very difficult. Other times, it tends to be relatively easy. A lot of it depends on the technology being used,” Cpt. Cohen explained.

In Thursday’s incident, the suspect appeared to be disabling the social media account throughout the day. Cpt. Cohen said suspect are catching on to technology and how to throw off police.

“One of the things we’ve seen over the last couple years is an increase in the number of apps that are available that actively work to try to conceal the identity of the people involved in the communication,” he said.

The suspect also allegedly tagged others in the social media posts. Some of the people he tagged told FOX59 they do not know the suspect or know how their names were found. Multiple people posted comments on the suspect’s threats. Experts say it’s best not to respond.

“They shouldn’t engage that person that is threatening them in communication. Generally it doesn’t add any benefit it can actually instigate a person to make more threats to you,” Cpt. Cohen said.

While suspects are getting more technologically savvy, Cpt. Cohen said so are police and it’s just a matter of time before law enforcement catches on to this person.

“To any viewers that might choose to make a threat that might choose to try to commit crimes over the Internet, likely we are going to be able to find out who you are and locate you,” Cpt. Cohen said.

If the suspect is found, he or she will likely be charged with terroristic threats. The charge is a felony.
