Rome: A grieving Russian mother stuffed the body of her anorexic ex-model daughter into a suitcase and threw it into the sea after she starved to death, Italian media said on Wednesday.

The wasted remains of Katerina Laktionova, 27, were discovered late last month after fishermen spotted the small black suitcase in the waters off Rimini, a city on Italy’s Adriatic coast where her mother worked as a caregiver.

An initial murder probe was dropped after an autopsy showed the young woman had died of hunger days before her body was dumped.

Laktionova’s mother, 48, who flew back to Russia shortly before the body was found, made a tearful confession to Russian authorities in which she admitted she had sat in shock over her daughter’s corpse for days before deciding to dispose of it.

The Corriere della Sera daily said investigators were tipped off by a friend of the mother, who feared foul play after the suitcase was found.

He said the caregiver had called him claiming to be in Russia in the run-up to the discovery, but the calls were made from Italy.

The ex-model, who had been hospitalised for a short period in Italy in 2015, had spent her final days lying in bed in the dark, and was believed to have died at least a week before she was put in the suitcase, the daily said.
