A four-year-old girl drowned after being forced into a car with the bullet-riddled bodies of her parents and pushed into a lake by their killer.
Konstantin, 35, and Inna Larkov, 32, drove two hours across Crimea with their daughter Arina to buy a new car the father found online.
They arrived in the small village of Geroevskoe and were met by two men who claimed to be the owners of the new car.
Raven Samar confessed to the vile crimes against the family and even gave police a demonstration at the scene.
He met the family and asked them to give him a lift to his car.
Next he told them he was feeling unwell and asked to stop near a small remote beach.
Samar then pulled out a Makarov gun and forced Larkov to give him the money for the car.
Dad-of-one Larkov fought back and as a result was shot five times. Then Samar turned his gun on Ms Larkov and shot her in the chest and head.
The killer and an accomplice then pocketed the 255,000 RUB (£3,236) Mr Larkov brought to buy the car, along with his phone, and stuffed the bodies inside.
They then forced the terrified girl, who watched both of her parents being murdered, back into the car before rolling it into the lake.
Samar went to work at his job as a prison guard in Sevastopol just hours after the brutal murders, carrying the jail-issued gun he shot his victims with.
Police tracked Samar - who is the father of a young child - and he made a full confession and demonstrated at the crime scene how he killed the family, said police.
Police then towed the car out of the water. No bullet wounds or injuries were found on the child's body. She was forced into the car alive and drowned.
Police were alerted when worried neighbours called the police when the family failed to return home or answer their phones.
Neighbours put up missing person posters around their home town of Feodosia after hearing the family dog whining from thirst and hunger.
Detectives tracked him down a week later and he made a full confession, even leading them to the bodies and reenacting the sickening crime.
Samar faced life in prison but the brutality of his crimes prompted many Crimeans to lobby for capital punishment to be reintroduced.
