On July 1, 2026, Worcester Police Detective Sergeant William Pero and Detective Jay Magarian of the Unresolved Homicide Unit traveled to Tampa, Florida, to assist in the arrest of 23-year-old Jayden Montes.

Through their continued investigation, detectives assigned to the Unresolved Homicide Unit, with the assistance of the Worcester County District Attorney’s Office, developed probable cause to charge Montes with the 2022 murder of Jazmin Rosario. She was just 17 years old when she was shot and killed just days before her birthday. As a result of those investigative efforts, an arrest warrant was issued charging him with Murder.

With the assistance of the U.S. Marshals Fugitive Apprehension Central Florida/Caribbean Task Force, which included the Tampa Police Department, St. Petersburg Police Department, U.S. Marshals Service, Pinellas County Sheriff’s Office, and Pasco County Sheriff’s Office, Montes was taken into custody without incident shortly after 6:00 a.m.

“While this arrest can’t undo the pain of Jazmin’s loss for her loved ones, it is an important step toward justice," said Worcester Police Chief Paul Saucier. "The Worcester Police Department’s Unresolved Homicide Unit and every Worcester Police Officer will continue to work tirelessly each day to hold those responsible accountable.”
