The man arrested for the killing of 42-year-old Carmen Lizet Puch of Reston has reportedly confessed to the crime. Puch was found Monday morning lying next to her car in a Great Falls parking lot near Difficult Run Trail. She had trauma to her upper body and was pronounced deceased at the scene.

Alexis Antonio Cedillos-Campos, 19, was taken into custody Wednesday and charged with second-degree murder. He offered homicide detectives a “full confession for what transpired,” according to Fairfax County Police Chief Kevin Davis.

At a Wednesday press conference, Davis said that Cedillos-Campos and Puch were coworkers at a restaurant and had an “intimate relationship.” He said that Cedillos-Campos left the restaurant on the night of the murder with a fixed blade knife, latex gloves, and a water bottle that he took from the restaurant. He emptied the water bottle and filled it with gasoline from his motorcycle. “All very premeditated,” Davis said.

Davis said that Puch and Cedillos-Campos met at the parking lot and Cedillos-Campos “stabbed our victim repeatedly and eventually doused her in gasoline and tried to set her on fire.”

Fairfax County police coordinated with Prince George’s County’s police department and the U.S. Marshalls Service to locate and apprehended Cedillos-Campos in Lanham, Maryland. He is being held at the Prince George’s County jail while awaiting extradition to Fairfax County.
