The Incident
Police say a 19-year-old man stabbed 42-year-old Carmen Lizet Puch to death while she sat in her car in the parking lot of Difficult Run Park, Great Falls, Virginia. A runner found Puch unconscious; officers discovered multiple stab wounds, gasoline on her body, and pronounced her dead at the scene. The suspect, identified as Alexis Antonio Cedillos-Campos, was arrested later that morning in Lanham and is being held in Prince George’s County jail pending extradition.
Background & Context
Investigators found that Puch and Cedillos-Campos worked at the same local restaurant and had an intimate relationship. Surveillance from the restaurant captured Cedillos-Campos retrieving a fixed-blade knife, black latex gloves and a water bottle later found filled with gasoline siphoned from his motorcycle.
