BEIRUT: State Prosecutor Hatem Madi said Friday that the investigation into last month’s assassination of one of the country’s top intelligence chiefs has been narrowed down to a range of possibilities.

“The margins have been tightened and the possibilities [of who stands behind the assassination] have been narrowed down,” Madi told The Daily Star, referring to the case of Brig. Gen. Wissam al-Hasan who was assassinated in a car bombing in October.

“Detectives have nearly completed analyzing evidence collected from the blast scene,” he said, adding that the evidence included images from surveillance camera footage.

A car bomb exploded in the Beirut district of Ashrafieh on Oct. 19, killing Hasan – who was the head of the Internal Security Forces Information Branch Brig – his driver and a woman. Over 100 people, including children, were also wounded in the blast.

Madi said some of the reports of forensic evidence and explosives experts have been submitted to him.

“Additional reports are still being reviewed,” he said.

However, Madi said he was yet to receive a report from the FBI, who dispatched a technical team to Lebanon to help analyze evidence.

“Evidence collected by the FBI team is still under analysis in specialized and highly advanced labs in the United States,” he said.

Madi said that while no arrests have been made, “every new piece of information is as good as a new lead.”
