GREAT FALLS, Va. — Authorities have pieced together the hours leading up to the death of 42-year-old Carmen Lizet Puch, whose body was discovered near Difficult Run Park on August 17. Using workplace video, phone records, and evidence from the crime scene, investigators have charged her 19-year-old co-worker, Alexis Antonio Cedillos-Campos, with second-degree murder. Cedillos-Campos was apprehended in Maryland two days after Puch’s body was found, marking a swift development in a case that has shocked the local community.
The investigation was initiated shortly before 7 a.m. when a jogger stumbled upon Puch near her 2011 Honda Civic in a gravel parking area. Responding officers noted injuries to her upper body, leading to an immediate determination of homicide. While police initially withheld certain details, it was emphasized that there appeared to be no randomness in the attack. Detectives quickly focused on Cedillos-Campos, publicly identifying him as a person of interest within 48 hours of the incident.
Police detailed a sequence of events that began long before Puch’s body was found. Cedillos-Campos and Puch, who had worked together at a restaurant in Herndon, were reported to have shared an intimate relationship. Evidence collected from the restaurant’s surveillance camera showed Cedillos-Campos leaving with a knife, gloves, and an empty water bottle. Authorities indicated that he used the bottle to transport gasoline from his motorcycle prior to their meeting, suggesting a premeditated encounter.
As the probe continued, a witness provided critical information, reportedly indicating that Puch had sent screenshots of conversations about their relationship to Cedillos-Campos’ girlfriend. This revelation purportedly incited conflict, prompting Cedillos-Campos to express a desire to harm Puch. This context of the relationship is yet to be corroborated in a court setting, as police have stated they are still working to fully understand the motive.
Reports suggest an early-morning phone call around 1:30 a.m. arranged a meeting between the two individuals, resulting in an encounter at Difficult Run. Investigators believe Puch was assaulted in or around her car, where she sustained multiple stab wounds. Following the attack, gasoline was reportedly poured on her, and attempts to ignite it were made, according to statements from police authorities.
The crime scene yielded black latex gloves and the empty water bottle detected with gasoline fumes, supporting the witness’s account of Cedillos-Campos’s pre-meditated actions. Furthermore, phone records corroborated the existence of the call between him and Puch prior to the incident, assisting police in developing a clearer timeline leading to her death. A preliminary autopsy categorized Puch’s death as a homicide due to multiple sharp-force injuries.
Adding complexity to the investigation, the witness claimed to have received a chilling phone call from Cedillos-Campos around 4 a.m., in which he allegedly stated he had “done it” before abruptly ending the conversation. This element remains under scrutiny and would be subject to examination in court should the case advance to trial. Following his arrest, Cedillos-Campos reportedly interacted with homicide detectives, with the police chief describing the conversation as revealing a “full confession” of events.
Detectives utilized various investigative methods to locate Cedillos-Campos, including reviewing surveillance footage and processing the parking area. Their efforts, in coordination with law enforcement agencies, culminated in his arrest on August 19 in Lanham, Maryland. Cedillos-Campos now faces charges of second-degree murder, accusations that have not yet been tested in a courtroom.
Puch, who resided in Reston and was identified as a devoted mother, has garnered support from victim specialists. Law enforcement has provided limited personal details about her, focusing primarily on the investigation itself. As the case unfolds, both the motivations behind the alleged crime and the precise events from that fateful night remain a pivotal focus for the authorities.
The prosecution’s case is developing based on a range of evidence, including surveillance footage, witness testimonies, and recovered items. However, the allegations against Cedillos-Campos remain unproven, and all details concerning the encounter at Difficult Run are still subject to determination in court. Fairfax County police continue to investigate Puch’s death as homicide, ensuring they uphold thorough inquiry as the judicial process moves forward.
