Forensic experts have detected traces of human semen in samples taken from a woman who alleges she was sexually assaulted by a plastic surgeon while sedated in an operating theatre in Murcia.
The discovery represents a potentially significant development in the investigation, although the biological material must still be compared with the genetic profile of the accused before any connection can be established.
The surgeon, identified only as David S., was arrested in December 2025 and has remained in custody after denying the allegations.
According to the report, specialists from Murcia’s Institute of Legal Medicine confirmed the discovery following analysis by the National Institute of Toxicology and Forensic Sciences in Madrid.
Vaginal and endocervical swabs were reportedly taken at Virgen de la Arrixaca University Hospital shortly after the alleged incident came to light. Culture and blood tests were also carried out. The woman is said to have told investigators that she had not had sexual relations since June 2024.
Her lawyer, Raúl Pardo-Geijo, had urged the authorities to obtain and examine the samples quickly amid concerns that they could eventually be destroyed. He said the latest result was important but stressed that the genetic comparison remained outstanding.
The alleged assault was reportedly witnessed and recorded by two healthcare workers who were inside the operating theatre.
The investigating magistrate at Court Number 4 in Molina de Segura has converted the preliminary investigation into formal proceedings, bringing the case closer to a possible trial before the Provincial Court.
The court has rejected the surgeon’s application for release, citing a possible risk of further offences. A request by the accused to learn the identities of the patients making allegations against him was also refused.
A second woman previously came forward during the investigation. The surgeon reportedly faces two additional sexual assault allegations, one of which investigators have described as being supported by strong evidence.
The case remains under judicial investigation, and no final determination of guilt has been made.
