Joan Vila i Dilmé

Aida Vila Dilmé (born Joan Vila Dilmé, 26 September 1965), known as The Caretaker of Olot and The Angel of Death, is a Spanish serial killer and nursing assistant. She is responsible for at least 11 murders committed at the Fundació La Caritat in Olot between August 2009 and October 2010, with all her victims being elderly patients aged 80–96.

In 2014, she was found guilty by the Supreme Court of Spain and sentenced to 127 years and a half imprisonment for her crimes. After her arrest, Vila would acknowledge that throughout her childhood and youth, she felt like "a woman trapped inside a man's body" and that her homosexuality had influenced some of her habits.

Adulthood For a while, Vila occupied a small apartment in Castelló d'Empúries, and later opened a hairdressing salon named Tons Cabell-Moda in Figueres, but it quickly shut down, allegedly because her partner had scammed her. She later changed a myriad of jobs in the plastics, textile and skiing industries, and even owned a restaurant, the Casino de Peralada. In addition to this, she also took on training courses in cooking, chiropractic, dressmaking and reflexology. In addition, she consumed many energy drinks (often mixed with anxiolytics and alcohol), was maniacal on cleanliness and followed a compulsive diet. She also had multiple books on paranormal phenomena and death, which she acquired from a local hairdresser friend. After Vila's arrest, she was ordered to undertake a psychiatric evaluation, which determined that she suffered from severe depression.

Murders Initial murders At the beginning of 2006, after having worked in Banyoles and Salt, Vila was hired as a nursing assistant at the Fundació La Caritat nursing home in Olot, next to the Fluvià River. At the time the home was run by psychologist Joan Sala, who saw no harm in the new employee. Each death occurred within months of the last one, with several relatives reporting that their loved ones had died an agonizing death, with some of them bleeding from the mouth. The victims, who were predominantly women aged 80–96, were Rosa Barbures Pujol, Francisca Matilde Fiol, Teresa Puig Boixadera, Isidra García Aseijas, Carme Vilanova Viñolas, Lluís Salleras Claret, Joan Canal Julià i Montserrat Canalias Muntada.

Later murders From 2006 up until the autumn of 2010, Vila lamented to her colleagues that 'all the old women were dying on [her]'. The team, led by inspector Josep Monteys, concluded that the elderly woman couldn't have been able to ingest the detergent herself and that they might be dealing with a homicide. Shortly thereafter, Mossos agents examined the security feed, noticing that one of the nurses locked himself in the supply closet shortly before Gironès i Quintana was killed. After questioning the rest of the staff at the facility, the police brought in Vila for further interrogation, whereupon she immediately confessed to two of the murders. Subsequently, she was charged with them and remanded to await trial. Because of this, it was impossible to verify whether there were more victims or not.

Trial in the Provincial Court of Girona Vila's trial began at the Provincial Court of Girona on 27 May 2013, with her initially confessing that she didn't want to hurt the old women and was relieved to see them dead. She was faced with the possibility of a sentence of more than 200 years imprisonment for 11 counts of the murder, the last 3 of which were aggravated. The prosecution argued that the killer took advantage of the times when there were few other staff members, and with her victims being unable to defend themselves, she was able to freely kill without any hindrances. While the imposed sentence was 127, the maximum penalty established by criminal law amounted to 40 years imprisonment, which Vila had to serve at the Puig de les Basses Penitentiary Center in Figueres.

In economic terms, the total amount of compensation for the murders amounted to 369,000 euros for Vila from public liability relating to them. Aside from her, the judge also imposed sanctions on La Caritat, based on an article from the Criminal Code of Spain that stated that juridical persons who own an establishment where a worker commits a crime are also liable in civil lawsuits. However, the financial compensation, of between 6,000 and 39,000 euros depending on the relationship of each family member to the victim, was covered by the Zurich Insurance Group.

In April 2026, it was reported that Vila had come out as transgender, changed her name to Aida, and was undergoing hormone therapy. It was also reported that she was awaiting gender reassignment surgery.
