ROCHESTER, N.Y. (WROC-TV) - UPDATE: Rochester Police on Thursday said they believe there is only one suspect in the murder plot, and that person is local, but not a student.
Investigators also believe the situation was an isolated incident, and no harm was to come to other students or teachers within the district.
Deputy Chief Scott Peters said, "this was a specific threat directed towards one individual. So this wasn't just somebody who was going to take the gun and have school violence or shoot randomly."
Rochester Police are still actively investigating the incident, and no one has been taken into custody.
School district officials declined to comment on Thursday.
ORIGINAL: An attempted murder plot targeting a Rochester City School District student has been averted -- thanks to a Pennsylvania corrections officer.
Police say an officer at the Allenwood Correctional Facility was doing routine monitoring of inmate phone calls.
The officer heard two calls where an inmate was discussing a possible hit on a RCSD student.
Another investigator determined the inmate was trying to stop a hit on a student.
Rochester police were notified and responded to Rochester International Academy on the Jefferson Campus on April 5. The school was placed on lockout.
Police found a handgun under a dumpster on school grounds -- right where the inmate said it would be.
No one has been charged in connection with the weapon.
