Overview

  • Jury selection began July 14, 2025, at Chicago’s Leighton Criminal Court Building for Steven Montano, 21, who is charged with first-degree murder and other felonies in the March 1, 2023 slaying of Officer Andrés Vásquez Lasso.
  • Prosecutors contend Montano grabbed his girlfriend’s phone and a weapon during a domestic dispute and fatally shot Lasso after the officer pursued him from a Southwest Side residence.
  • Jurors are expected to view body-worn camera footage from Lasso’s patrol unit, reflecting Chicago’s department-wide camera adoption under reforms prompted by the Laquan McDonald case and the SAFE-T Act.
  • Montano’s trial is the first jury case in a slain Chicago officer’s killing since one of the gunmen in Officer Ella French’s death was convicted late last year.
  • The proceedings come as the Chicago Police Department grieves multiple on-duty fatalities and reviews response protocols for domestic calls and friendly-fire prevention.
