The case has eight accused, including Runi’s friend Tanvir Rahman. The other accused are house security guards Enam Ahmed alias Humayun Kabir and Rafiqul Islam, Bokul Mia, Mintu alias Bargira Mintu alias Masum Mintu, Kamrul Hasan Arun, Palash Rudra Pal and Abu Sayeed. Although each of the accused has been remanded several times during the investigation, none has made a confessional statement before the court.

The journalist couple was brutally murdered at their rented apartment in West Rajabazar, Dhaka, at  night of February 11, 2012. Sagar Sarowar was the News Editor of Maasranga Television, while Meherun Runi was a Senior Reporter at ATN Bangla. Their bloodstained bodies were recovered from their residence the following morning, sparking nationwide outrage and demands for a swift investigation.

Following the murders, Runi’s brother, Nowsher Alam Roman, filed a murder case with Sher-e-Bangla Nagar Police Station. The investigation was initially conducted by a sub-inspector of the police station before being transferred to the Detective Branch (DB) of Dhaka Metropolitan Police four days later. After more than two months of investigation, the DB failed to identify the killers or establish the motive behind the crime.

On April 18, 2012, the investigation was handed over to the Rapid Action Battalion (RAB) as per the High Court directive. Despite years of investigation under the elite force, the case remained unresolved, with repeated delays in submitting the investigation report.

Subsequently, on October 17, the Public Security Division of the Ministry of Home Affairs issued a gazette notification forming a four-member high-level task force headed by the chief of the Police Bureau of Investigation (PBI) to oversee and complete the long-pending investigation.
