A Greek woman, Roula Pispirigou, received two additional life sentences for murdering her infant daughters, Malena and Irida, after being convicted last year of killing her 9-year-old daughter, Georgina.

The court found she suffocated the children to prevent her husband from leaving.

Pispirigou maintains her innocence and plans to appeal, CBS News has reported.

The case, which shocked Greece, was reopened after Georgina’s murder led to a reassessment of her siblings’ deaths.
