Teen charged in connection to missing gun at Forest View Educational Center in Arlington Heights in court

One of the two teens charged with allegedly taking and concealing an Arlington Heights school resource officer's gun is expected in court on Thursday. 

Arlington Heights police said that Juan Pablo Sanchez Jaramillo, 18, of Mount Prospect, was charged with unlawful possession of a weapon in a school. A 17-year-old was also charged with possession of a stolen firearm and unlawful possession of a weapon in a school, and a misdemeanor count of theft of lost or mislaid property.

Jaramillo is scheduled to appear at a detention hearing at the Rolling Meadows Courthouse at 9 a.m.

According to police, the officer removed his gun while using the bathroom at the Forest View Educational Center just before classes ended on Monday. After class dismissal, the officer realized the weapon was missing.

Police said detectives determined that Sanchez, who is a student at the school, took the gun, concealed it, and removed it from school grounds. It was further alleged that he gave the firearm to the 17-year-old in a neighboring community. 

Police said during a search of that area on Tuesday, a tactical flashlight that was attached to the gun before it had gone missing was found. 

The 17-year-old was arrested, but officers did not recover the missing gun, according to police. 

The school resource officer is on administrative leave amid the ongoing investigation.
