On February 1, 1930, the doctors advised that Marie-Louise be housed in a specialized establishment, explicitly forbidding Pierre Laget from visiting her, as they suspected he had attempted to poison her. After two days without contact with Pierre, Marie-Louise's condition improved. She later confided to her doctor that her brother visited her every day to treat her with some tea, but she got worse and worse with each day after drinking it. On the advice of Dr. Roulleau, Marie-Louise filed a complaint against Pierre for attempted poisoning, in which she was joined by the Alexandre family.
