 Lhermitte 's last victim was her eldest daughter , Yasmin . The mother called over Yasmin and told her she had a surprise for her , just like she had done with Myriam . Lhermitte attacked Yasmin from behind as she entered the office , but Yasmin was able to dodge the knife by diving to the ground . After a struggle in which Yasmin suffered multiple stab wounds , Lhermitte stabbed her in the back and slashed her throat . With her children dead , Lhermitte then attempted to kill herself by falling on her knife . When she realized that the wound would not be fatal , she wrote " call the police " in red marker on her door and called emergency services to the house . Investigators found the four children tucked in their beds , some with stuffed toys in their arms .
