Oxana Mironova, 33, and her husband Maxim Lyutyi, 43, starved their baby to death.

The father, Maxim, was a raw food blogger. He convinced his wife Oxana that the baby should be fed sunlight. As a result, the baby starved to death.

The parents were sued.

Oxana's mother Galina accused the husband and wife of running a "cult" and said: "They experimented on the child, they wanted to feed her entirely on the sun and then advertise to others that you can eat this way. I felt everything and told her that Maxim was crazy, but she didn't listen to me. Oxana lived there like a guinea pig. Each time she became cold towards me.... She was his slave," he said.
