Costa Rica’s Judicial Investigation Organization (OIJ) arrested an American citizen on Tuesday in connection with the killing of a woman whose body was found on a Guanacaste beach over the weekend.

The suspect, identified by authorities by the last name Page, 49, was taken into custody by agents of the OIJ.

According to OIJ Director Michael Soto, the investigation began Saturday at about 10 p.m. after an emergency call reported the discovery of a woman’s body on Junquillal Beach, in Guanacaste province.

Authorities said the victim’s body showed multiple stab wounds, which are believed to have caused her death.

Investigators later identified the victim as an Argentine woman about 35 years old, surnamed Cadento.

Forensic agents conducted examinations at the scene with the assistance of trained K-9 units to search for traces of human fluids and other evidence.

The investigation determined that the woman had been seen on Friday at a party held at Page’s residence, which is also located near Junquillal Beach.

At around 8 p.m. Tuesday, OIJ agents executed a search warrant at Page’s home, where they carried out a series of forensic tests, including the use of luminol, a high-technology chemical agent used to detect blood traces.

Authorities reported finding blood evidence on the property. Based on those findings, investigators identified Page as the presumed perpetrator of the crime.

Page was arrested as the main suspect in the case and transferred to the Guanacaste Public Prosecutor’s Office, where he is expected to be questioned by judicial authorities. A judge will later determine the pretrial measures to be imposed during a court hearing. Page is accused of the murder of Cadento.

In addition to the arrest, authorities seized several items considered relevant to the investigation, including clothing, cellphones and other evidence.

According to the U.S. Embassy’s website, American citizens arrested abroad are entitled to consular assistance. Once notified by Costa Rican authorities, a U.S. consular officer visits the detainee to check on their well-being, review the conditions of the arrest and provide information on local legal procedures, including a list of attorneys.

If requested, consular officials may also notify family members or friends, help facilitate the transfer of funds for legal or living expenses, and serve as liaisons with relatives.

However, the embassy notes that consular officers cannot act as attorneys, provide legal representation or influence the release of arrested U.S. citizens.

For detainees facing lengthy prison terms, consular officers are required to conduct visits at least once every three to four months.

The OIJ operates under Costa Rica’s Supreme Court of Justice and serves as the country’s primary criminal investigative agency, with nationwide police authority.
