International Manhunt Underway for Arizona Man Suspected of Killing, Burying Parents

An international manhunt is underway for Matthew Christopher Flores Semyonov, 27, an Arizona man suspected of murdering his parents and burying their remains in the backyard of their family home, according to Idaho News. The U.S. Marshals Service has identified him as a fugitive and believes he has already fled the country.
The Avondale Police Department discovered "indications of foul play" at the home, including large amounts of blood and evidence that someone had tried to clean it up, KOMO News reported. Authorities are urging the public not to approach Flores Semyonov, warning he should be considered dangerous.
Avondale police responded to the family's home and made a grim discovery. Officers found significant amounts of blood inside the residence, Bakersfield Now reported. Evidence at the scene also showed someone had made a clear attempt to clean up the blood before police arrived.
The remains of Flores Semyonov's parents were found buried in the backyard of the home. Police declared the scene a crime scene and began a full investigation. The exact cause and manner of the parents' deaths have not yet been publicly confirmed by authorities.
The U.S. Marshals Service District of Arizona has taken a lead role in the search, Fox 17 reported. Marshals believe Flores Semyonov fled the United States after the killings. The case has now escalated into an international manhunt, with agencies working across borders to track him down.
Authorities have not publicly disclosed which country or countries Flores Semyonov may have traveled to. The Marshals Service is known for its fugitive operations and has coordinated with international law enforcement agencies in similar high-profile cases before, according to Fox San Antonio.
Law enforcement officials are urging the public to stay away from Flores Semyonov if spotted. The U.S. Marshals Service labeled him dangerous, WWMT reported. Anyone with information on his whereabouts is asked to contact authorities immediately rather than try to intervene.
The warning reflects the serious nature of the alleged crimes. Killing two people and attempting to conceal the evidence points to a calculated suspect, investigators suggest. Tips from the public have played a key role in past Marshals fugitive captures, and officials are counting on that again here, according to WGME.
Flores Semyonov is 27 years old and was living in Arizona before the alleged killings. Beyond his age and name, authorities have released limited personal details about him publicly, News Channel 9 reported. His dual surname suggests possible mixed heritage, which may factor into the international scope of the manhunt.
No charges have been officially confirmed in public records reviewed by outlets covering the story. However, the U.S. Marshals' involvement and the fugitive designation make clear that investigators believe Flores Semyonov is responsible for his parents' deaths, according to WGXA.
