Investigations
Both the US and the Sudanese government have announced investigations as to the causes of the shooting and efforts to find the perpetrators. The US effort will consist of a joint State Bureau of Diplomatic Security and Federal Bureau of Investigation team.
Four days after the murders, a previously unknown militant group, Ansar al-Tawhid (Companions of Monotheism) claimed responsibility via a post on a website used by Islamists.
In September, five Sudanese men admitted their roles in the shooting in filmed confessions.
On June 24, 2009 four men were sentenced to death by hanging for the killing. A fifth man received a two-year prison term for providing the weapon used in the attack. The convicts were identified as Abdelraouf Abu Zaid Mohamed Hamza, Mohamed Makawi Ibrahim Mohamed, Abdelbasit Alhaj Alhasan Haj Ahmad, and Mohanad Osman Yousif Mohamed.
In June 2010, the four men broke out of prison, killing a police officer and wounding another during their escape. Sudanese authorities then issued a global Interpol warrant for their arrest. However, only one has so far been recaptured.
