Matthew Flores, 27, is currently the prime suspect in the double homicide of his parents, Hector and Larissa Flores, both in their 60s. Authorities believe the suspect has fled the United States, triggering an international manhunt. The investigation began on August 4, 2026, when the Avondale Police Department responded to a welfare check request from relatives who were unable to reach the family at their home in Litchfield Park, Arizona. Upon arrival, officers discovered the property empty and found a large amount of blood inside the residence, along with evidence suggesting an attempt to clean the scene. Homicide detectives were subsequently called to the scene to examine the evidence. The investigation led officers to the backyard, where they utilized a mini excavator to unearth the remains of two individuals buried in shallow graves on August 6. Pending autopsies by the Maricopa County Medical Examiner's Office have identified the victims as Hector and Larissa Flores. The bodies were found in a state of decomposition, though the exact time of death remains under investigation. Following the discovery of the bodies, the Avondale Police Department named Matthew Flores as the prime suspect. Authorities announced that Flores is believed to have fled the country shortly after the alleged murders, though the specific destination remains unknown. The case has escalated into a joint effort involving the Avondale Police Department, the FBI, and the US Marshals Service. The Flores Semyonov family released a statement expressing devastation and requesting privacy while cooperating fully with law enforcement. Neighbors in the typically quiet Litchfield Park neighborhood expressed shock and confusion over the violent crimes that occurred in their community. Investigators are urging anyone with information regarding Flores's whereabouts to contact the Avondale Police Department. The situation remains active as federal and local authorities work to locate the suspect and bring him back to Arizona for prosecution.
