Overview

  • Prosecutors classified the August 1 killings of Lauren Semanchik and Tyler Webb as a targeted act of domestic violence with no ongoing risk to the community.
  • Semanchik, a 33-year-old veterinarian, and her 29-year-old partner, volunteer firefighter Tyler Webb, were found shot inside her Franklin Township home.
  • Video footage shows Ricardo Santos’s white 2008 Mercedes closely following Semanchik’s vehicle from Long Valley Animal Hospital to her Pittstown residence before the shootings.
  • Santos, a New Jersey State Police lieutenant who served on the governor’s security detail, was discovered dead by a self-inflicted gunshot in his parked Mercedes at Johnson Park in Piscataway.
  • Semanchik had reported stalking and harassment by Santos after their September breakup and was denied a restraining order, highlighting gaps in victim protection.
