Despite the many unknowns that still surround the circumstances of the murder, the investigation into the death at Teatinos’ Amsterdam street apartment in the Oviedo district is gradually shedding light on a brutal crime. Early days of the inquiry have produced new certainties, including DNA samples currently undergoing analysis in the lab, which are expected to clarify the sequence of events surrounding the homicide.
The traces in question must be recent and were collected from sensitive areas of the crime scene, the body itself, or locations where the body was discovered. As reported yesterday, forensic analysis indicates that Tatiana Coinac died between Thursday and Friday of last week, with the body found on Sunday morning. The authorities have established that the killer struck in one room, then moved the victim to another, tying the person to a bed before transporting them to the bathroom. This sequence is supported by initial crime scene reconstructions and forensic timing of the evidence collected.
Coinac was found in the tub when police arrived. Later information revealed that the perpetrator took steps to wash the body thoroughly and to erase traces, or to recreate an arrangement that differed from the actual murder scene. This behavior, described in investigative jargon as a forensic conscience, combined with the extreme brutality of the act, strengthens the working hypothesis that the offender may have operated in other settings and left additional DNA signatures behind. Authorities are assessing the possibility of a history of violence against women as part of the suspect profile.
Finding the killer’s genetic fingerprint is a priority in cases of this nature. Investigators from the Specialized and Violent Crimes Unit, the UDEV Center, which represents the national police’s elite investigative team, are cataloguing the genetic profile into the CODIS database to seek matches. The unit has previously brought resolution to other cases by leveraging CODIS confirmations. In recent years, the unit has solved several difficult cases, including prior homicides linked to serial offenders who traveled through Spain, with investigations touching locations such as Elche and Orihuela. When CODIS matches emerged, the suspect was located in Moscow, where similar acts had previously netted sentencing and conviction. This pattern underscores the role of genetic databases in connecting distant offenses and building a comprehensive picture of criminal activity across borders and time.
