Overview
- The Jefferson County Sheriff's Office closed the case Wednesday after a nearly five-month investigation, pending any new evidence.
- Investigators identified the weapon as a Smith & Wesson .38 Special first purchased in Florida in 1966 and traced its ownership with help from the FBI and ATF.
- A letter from the family's attorney said the revolver belonged to a grandparent and was kept out of sight in a large locked safe.
- DNA testing found no link between the parents and the firearm, and investigators said they could not meet the elements to pursue charges under transfer or secure-storage laws.
- The Sept. 10, 2025 shooting wounded a 14-year-old student and 18-year-old Matthew Silverstone, and community support remains available through the Evergreen Resiliency Center.
