On June 29, 2017, Officer Guzman was involved in a shooting incident where he fired multiple shots into a vehicle occupied by Marta Sanchez, Stephanie Lopez, and Dominic Martinez without giving a warning and without being in imminent danger. This resulted in severe injuries to the occupants, including the death of Stephanie Lopez. A civil rights lawsuit was filed against Officer Guzman and other officers involved, alleging excessive force and constitutional violations. The case highlighted concerns about the use of force and training within the department. ([casetext.com](https://casetext.com/case/sanchez-v-city-of-littleton?utm_source=openai))
