Mikali, with Elemu, Edward Vossler, and the other terrorists, held First GentlemanHenry Taylor hostage until Dubaku arrived. At 3:26pm, Elemu reported to Dubaku that Taylor's hand wound was difficult to close, so Dubaku told him to get a blowtorch from Mikali to cauterize it.
Mikali was killed in the raid on the hideout by Jack Bauer and Renee Walker, and they later confirmed to the President that all the men there were dead.
