Sam Bockarie, widely known as Mosquito (2 October 1964 – 5 May 2003), was a leading member of the Revolutionary United Front (RUF) in Sierra Leone. Bockarie was infamous during the Sierra Leone Civil War for his brutal tactics, which included amputation, mutilation, and rape. He earned the nickname "Mosquito" for his ability to attack when his enemies were off-guard mainly during the night. During his service in the RUF, he befriended future Liberian president Charles Taylor, and RUF commander Foday Sankoh. When Sankoh was imprisoned from March 1997 until April 1999, Bockarie served as commander of the RUF in his place.
After fleeing Sierra Leone in 2000, Bockarie joined with Taylor's Anti-Terrorist Unit (ATU) in Liberia, (Bockarie moved to Liberia under an ecowas agreement with the then Sierra Leonean President. There is no proof that he joined the Liberian A.T.U, eventually moving to the Ivory Coast, where he participated in the rebellion led by Guillaume Soro in connection with the Gbatala base headed by Charles Taylor. Under international pressure, Taylor initiated a policy of disengagement with regards to former RUF leaders, and officially expelled Bockarie from the country, although he was reported to have continued to travel freely between Liberia and Côte d'Ivoire. To secure peace in the Ivorian Civil War, and increase trade with president Laurent Gbagbo, Taylor is said to have asked Bockarie to assassinate Ivorian rebel leader Félix Doh, who was killed in April 2003.
As early as 27 April 2003, Bockarie's actions had brought him back into Liberian territory, where Charles Taylor was now President. The UN received news of Bockarie's presence, and put pressure on Taylor to apprehend him and turn him over to the SCSL. Late in the day on Monday, 5 May 2003, Bockarie was killed in what was officially reported to be a shootout with Liberian forces. There is some controversy that, since Bockarie's testimony at the SCSL could have implicated Taylor, Taylor sent the troops to find and kill Bockarie, rather than to arrest the man (Perspective, 2003). In any case, after a short time of confusion over the veracity of reports on Bockarie's death, proceedings against Bockarie by the SCSL were terminated on 8 December 2003.
