Security guards who posed as cops to rape a teenage girl before murdering her and her boyfriend and throwing their bodies in a river have been seized by police.

Seyma Demir, 18, and her boyfriend Hasan Aydogan, 21, went missing last week and their families went to the police to report their disappearance.

Police launched a search and found a vehicle used by the couple abandoned in a forested area in the district of Agbayir, in the Turkish province of Kirsehir.

Mobile phones, coats and a bag containing Seyma’s personal belongings were found inside the vehicle.

After a tip-off on the evening of 26th March, police teams started a search on the edge of the Kizilirmak river, near the village of Kortullu, about 40 kilometres (25 miles) from the centre of the city of Kirsehir.

During the night-long search, Seyma’s lifeless body was found by the river, and two male security guards were detained as suspects.

The men – identified as Sami Aydogan and Sefik Ekici – allegedly spotted Hasan and Seyma in a remote area where they were drinking, and introduced themselves to the couple as police by showing their guns.

The suspects allegedly told the young couple that they were “detained” for an undisclosed reason, cuffed their hands behind their backs, put them in their cars, and took them to the shore of the Kizilirmak river.

The suspects, who continued to drink alcohol there, allegedly first raped the teenage girl and then shot her with a single bullet in the back of the neck and threw her into the Kizilirmak river.

Afterwards, they allegedly shot and killed Hasan and also threw his body into the river.

The authorities have reportedly determined that Sami Aydogan, who has allegedly confessed to raping and murdering Demir, tried to destroy the evidence by having his car valeted after the murder.

It was also reported that Sefik Ekici, who has denied the accusations, is the nephew of the mayor of Kirsehir, Selahattin Ekicioglu.

According to reports, the young woman’s corpse was found thanks to air bubbles trapped in her coat, which helped her body float to the river bank.

Seyma was buried in the village of Akcaagil, in the province of Kirsehir, on 28th March, following an autopsy performed in Ankara.

The search for Hasan’s body continues.

It is unclear whether the suspects will remain in preventive custody as the investigation continues.
