1 In Custody, Gun Cop Lost In School Bathroom Still Missing: Arlington Heights PD

ARLINGTON HEIGHTS, IL — One person is in custody as the investigation continues into the whereabouts of a gun lost or mislaid by a school resource officer Monday while they were using the restroom at Forest View Educational Center. The officer, a member of the Arlington Heights Police Department, has been placed on administrative leave pending a formal internal affairs investigation

Classes at the school are set to resume after being canceled Tuesday as police said they're confident the gun is no longer on campus at 2121 S. Goebbert Road. They added that there are no known threats at this time.

"The recovery of the firearm and apprehension of those responsible for the theft remain the highest priority as the investigation continues to evolve," Arlington Heights police said Tuesday night.

Police said they have "narrowed the scope" of their investigation to a small group of people connected to the case, including the person in custody, who they say is being cooperative.

The officer, who had removed his firearm from his duty holster while using the restroom, realized the firearm was missing shortly after students were dismissed for the day.

After an unsuccessful search of the bathroom for the weapon, police said hallway surveillance images were immediately reviewed, which determined a limited number of persons entered the restroom. Soon thereafter, notification of a firearm theft was made to school and police officials.

Authorities said the Village and AHPD have been in close contact with school officials throughout Tuesday, "collaboratively sharing pertinent information related to the case and reviewing safety protocols."

Uniformed police will remain on campus throughout the school day, following safety protocols, including restricted access and metal detector screening.

"We value the trust our community places in the Police Department and its officers," Arlington Heights Police Chief Nicholas Pecora said. "We remain committed to resolving this situation and ensuring that all responsible parties are held accountable, including matters within our own organization."

The Arlington Heights Police Department said it will continue to pursue active investigative leads and is asking any member of the community with information regarding this incident to contact detectives at 847-368-5300.
