Three Murders over Three Years in Osmaneli

SolvedSources: ALast updated: 14 October 2026

Between 2006 and 2009, three men were killed in the Osmaneli district of Bilecik: Arif Sivri on 1 November 2006, Ragup Işık on 13 March 2008 and Necdet Badem on 30 May 2009. When detectives established that the same gun had been used to kill Işık and Badem, they linked the cases and questioned around 200 people in the district. In January 2010, a car travelling from İzmir to Bilecik was tracked, and a male suspect in his late forties was arrested at the entrance to Osmaneli carrying a pistol believed to be the murder weapon. Under questioning he confessed to all three killings, claiming the victims had spread rumours about a woman he was in a relationship with. In a simultaneous operation, a woman accused of knowing about the killings and staying silent was also detained. As the trial outcome could not be confirmed, the suspects are not named.

Background

The district of Osmaneli in Bilecik, Turkey, was affected over roughly three years by three deaths whose connection was not at first apparent. Three men were killed with a firearm on 1 November 2006, 13 March 2008 and 30 May 2009: a television repairman, a kiosk owner and a market trader. Each case was handled separately, and the link between them was recognised only years later.

In a small district, the killings created a lasting sense of insecurity, and the families waited years for answers.

The victims were aged 38, 47 and 50. The first killing took place beside the Osmaneli–İznik road and the others in the district. That all three happened in the same area with the same weapon became meaningful to police only after ballistic comparison; until then each family faced its loss separately.

When the January 2010 detention became public it was received in the district as the first concrete answer to years of anxiety. What mattered most to the victims' families was that events be clarified before the law.

What happened and the investigation

The turning point was the discovery that the weapon used in the second and third killings was the same. Police connected the first killing as well and concluded that one person might be responsible. A special team was formed and spoke to around 200 people in the district.

In January 2010 a car travelling from İzmir was followed and stopped at the entrance to Osmaneli. A factory worker in his late forties was detained with a pistol said to be the weapon used. A woman was also detained in the same operation. According to statements reported in the press, the suspect said he killed the three men because they had spread gossip about her and slandered her; she was accused of knowing about the killings and not reporting them.

These accounts come from the suspect's statements in custody and should not be read as facts established by a court.

Legal process and legacy

The suspect was arrested on a charge of intentional killing. We could not find a reliable record of the trial's outcome, so no verdict is stated here. The case is remembered as a district-scale series of killings that were linked through ballistic matching of a single weapon.

The victims deserve to be remembered as people rather than case numbers: all three were ordinary tradesmen and workers of the district, and each left a family behind.

What is known of the proceedings against the suspect and the woman is limited to press reports, so this article includes only facts that could be verified. The case remains a local memory of three years of uncertainty in the district.
