Missing Russians were killed, claims suspects on arrest

Police have confirmed they have now arrested two men over the disappearance of two Russian siblings, with investigators preparing to take them to Khao Chi Chan in Chonburi to identify possible search locations, for the bodies.

Thana "Pong" Kerdthong, 43, and Thongchai "Thong" Srinil, 39, were detained in Wang Sombun district, Sa Kaeo, on 31 July 2026 after allegedly fleeing Bang Lamung district in Chonburi by motorcycle.

Arrests after search

The pair were suspects in a case involving joint night-time theft using a vehicle, or receiving stolen property. Police have also linked them to the disappearance of the Russian brother and sister, whose fate has remained unknown until the arrests.

Officers have continued searches all day, across suspected locations in the case. Following the arrests, police said the men would be taken to point out locations around Khao Chi Chan, in Chonburi.

Thongchai reportedly told police after his arrest, that Pong shot both Russian siblings dead before burying them on the mountain.

The suspected burial area is believed to be near the place where a motorcycle mudguard was found, on the route leading to Wat Yanasangwararam Woramahavihara.

Suspects make conflicting accounts

Pong reportedly admitted killing the younger brother by shooting him. He allegedly said the older sister died after being punched, claiming the attack was motivated by a desire to steal their motorcycle.

He further claimed that the bodies were buried to conceal the crime before the men fled. Pong denied that rape had taken place and that he only wanted to steal the motorcycle.
