[2] Indonesian police had accused Kwalik of being responsible for a series of shooting incidents and attacks targeting the United States mining company, Freeport-McMoRan, which operates large copper and gold mines on Papua Province.

[3] On December 16, 2009, Kwalik was shot in a police raid on one of his hideouts in the Gorong-Gorong neighborhood of Timika.

[5] Following Kwalik's death, the Free Papua Movement (OPM) in January 2010 appointed Jeck Kemong as the new Supreme Commander of its military wing, the West Papua National Liberation Army (TPNPB) and regional commander of Nemangkawi.
