The unfolding investigation into alleged drug theft and misuse at the Hospital Italiano began with a quiet confession. In February 2025, medical resident Mechi S. Learned from her colleague, Delfina “Fini” Lanusse, that Lanusse had consumed propofol alongside anesthesiologist Hernán Boveri.
A Friend’s Confession
Known to colleagues as “Pichu,” Mechi did not immediately report the incident. According to her later testimony in the propofol investigation, she initially sought to support Lanusse, cautioning her about the risks and attempting to navigate the situation privately. This initial approach was influenced by a close relationship with Lanusse, sharing commutes, social time, and professional responsibilities at the hospital.
Over the following months, Mechi observed concerning changes in Lanusse, including physical alterations and escalating patterns of substance use. She also perceived a developing relationship between Lanusse and Boveri characterized by a power imbalance. In June 2025, during an anesthesiology congress organized by Boveri, Mechi noted interactions that led her to believe their relationship extended beyond friendship.
Escalating Concerns
The situation grew more complex as Lanusse confided in Mechi that Boveri was already in a relationship with another colleague at the hospital, S.T. According to Lanusse, Boveri adjusted his work schedule to spend more time with her without raising suspicion from his partner. Despite these developments, Mechi continued to refrain from formal reporting, attempting to address the situation personally.
The turning point came in February of this year. Following a period of separation during January, Mechi noticed a significant change in Lanusse upon their reunion. A phone call on February 9th from Chantal “Tati” Leclercq, expressing concern over Lanusse’s well-being and inability to locate her, further heightened Mechi’s alarm. Leclercq also revealed an incident from five months prior – in September – that Mechi was previously unaware of: finding Lanusse in a distressed state at her apartment.
That same day, Mechi visited Lanusse’s apartment and found her disoriented, with a head wound, and in a condition that prompted Lanusse to explicitly ask for help, stating, “Hernán está loco.” Days later, on February 13th, Lanusse allegedly consumed propofol and ketamine, some of which, according to Mechi’s account, was against her will. This prompted Mechi, along with two other residents, K. P. And N. T., to alert hospital superiors, initiating internal reviews and contact with the Asociación de Anestesia, Analgesia y Reanimación de Buenos Aires.
This initial alert occurred just days before the discovery of anesthesiologist Alejandro Zalazar’s death on February 20th, which triggered a broader judicial investigation into the theft and misuse of hospital anesthetics. Lanusse is now facing legal proceedings as a secondary participant in fraudulent administration of medication. Mechi has not been implicated in the investigation.
