Luciani Aparecida Estivalet Freitas, a 47-year-old real estate agent who has lived in Florianópolis, Santa Catarina, since 2022, has been reported missing after family members noticed strange behaviors in her phone communications. The last known contact was on September 9, which prompted her family to contact the authorities. Her sister, Ariane Estivalet, residing in Canoas near Porto Alegre, expressed concerns that someone else may be using Luciani's phone, as her communication style has changed drastically.

Ariane recounts a noticeable shift in Luciani's behavior beginning on September 4, where she became increasingly monosyllabic in her messages and took an unusually long time to respond. The family grew suspicious about the language Luciani had been using, which included errors in Portuguese and an ironic tone that seemed out of character for her. They described her as someone who was previously very engaged and communicative in family group chats, highlighting the drastic and alarming change in her demeanor.

The family’s attempts to reach Luciani through voice calls or video chats were met with disregard or vague excuses, further heightening their concern for her well-being. Given the sequence of suspicious messages and her unexplained disappearance, the family has raised alarms, hoping for public assistance in locating her, while also speculating about the possibility of foul play involved in her case.
