Teen charged with murder for killing and attempting to burn body of co-worker after she sent screenshots exposing their affair to his girlfriend

Wednesday, September 2, 2026 -A 19-year-old Salvadoran man has been accused of killing his co-worker after she allegedly exposed their affair to his girlfriend.

Alexis Antonio Cedillos-Campos is accused of fatally stabbing Carmen Lizet Puch, a mother of a 3-year-old girl, near Difficult Run Park in Great Falls, Virginia, on August 17.

According to prosecutors, a co-worker told police that Cedillos-Campos had expressed his intention to kill Puch after she sent his girlfriend screenshots showing that the pair were having an affair.

The witness reportedly said Cedillos-Campos took a kitchen knife, latex gloves and a water bottle from the restaurant where he and Puch worked before heading to meet her at the park.

At around 4 a.m., he allegedly called the co-worker and said that “he did it,” which the witness interpreted as an admission that he had killed Puch.

Puch was later found with multiple stab wounds and gasoline on her body. Police said investigators believe Cedillos-Campos had attempted to set her body on fire after the stabbing.

Fairfax County Police Chief Kevin Davis described the killing as “very premeditated,” saying surveillance footage showed Cedillos-Campos preparing himself before leaving the restaurant.

Cedillos-Campos was arrested in Maryland on August 19 and has been charged with second-degree murder. He is being held without bond and is due back in court on November 30.
