The disappearance
Solsiret Rodríguez Aybar disappeared on August 23, 2016, from the Callao apartment complex where she lived with her family. For years, her parents pressed authorities to keep investigating while there was no confirmed account of what had happened to her.
Her remains were recovered in February 2020. That discovery transformed the case from a long-running disappearance into a homicide prosecution and brought renewed attention to the delays and failures that had marked the search.
The 2022 trial
In June 2022, the Permanent Collegiate Criminal Court of Callao convicted Kevin Alexander Villanueva Castillo of feminicide and sentenced him to 30 years. Andrea Regina Aguirre Concha was convicted of qualified homicide and received 28 years. Brian Villanueva Castillo and Yolanda Castillo García received shorter sentences for concealment-related conduct.
Those first-instance results are important historical facts, but they are not the final legal status of every defendant. The appeals substantially changed the case.
The appellate court changes the outcome
On January 15, 2024, the Second Criminal Appeals Chamber of Callao confirmed Andrea Aguirre's 28-year conviction for qualified homicide. It reversed Kevin Villanueva's feminicide conviction, acquitted him of that offense and instead sentenced him to six years for personal and real concealment. The court also reversed the concealment convictions of Brian Villanueva and Yolanda Castillo and acquitted them.
This distinction is central to responsible coverage. Kevin Villanueva was convicted of murder at trial, but that conviction was later overturned. Crime by Region therefore does not describe him as a presently convicted murderer while the prosecution challenge remains unresolved.
The Supreme Court split the case again
In September 2025, Peru's Supreme Court rejected Andrea Aguirre's cassation challenge. Her 28-year qualified-homicide sentence therefore became final in the criminal proceeding reviewed for this page.
The court took a different approach to Kevin Villanueva. It admitted the prosecution's cassation seeking to overturn his murder acquittal and the six-year concealment result, potentially opening the way to a new trial or other relief if prosecutors prevail.
Kevin's six-year term expired while review remained pending
The six-year concealment sentence imposed on Kevin was calculated from his February 2020 detention and expired on **February 13, 2026**. In February 2026, his defense requested immediate release while the Supreme Court cassation remained unresolved.
No later Supreme Court merits judgment was located in this review through August 27, 2026. This page therefore does not guess whether a new murder trial will ultimately occur. It records the legally safer position: Andrea Aguirre's murder conviction is final; Kevin's role in the homicide remains under extraordinary appellate review.
