Overview
- A welfare check on Aug. 4 led police to the Litchfield Park home and on Aug. 7 investigators dug up two decomposing bodies from shallow graves that were later identified as Hector and Larissa Flores.
- Officers discovered a large amount of blood inside the house and signs someone tried to clean it, findings that led authorities to treat the case as suspicious and to open a homicide probe.
- The U.S. Marshals Service obtained a federal warrant charging Matthew Christopher Flores Semyonov with unlawful flight to avoid prosecution and is leading an international search after authorities say he fled the country.
- Federal officials say Flores Semyonov should be considered dangerous and urge the public not to approach him but to report tips to official U.S. Marshals and local tip lines.
- Family members are cooperating with police, autopsies and forensic testing remain pending, and the case has drawn wider community attention including a statement from Cal Poly Pomona about Hector Flores’s role as an associate professor.
