Musa was an Indonesian who killed six people and seriously wounded a seventh at a hospital in Serui, a village on the island Yapen, Dutch East Indies on January 19, 1936.[1][2]

Musa was a Papuan missionary from Kerenui in southern Yapen. When it was found that he had embezzled collection money he was detached to northern Yapen, but he refused to make the journey and returned to Ansus. There he was reported to the missionaries, after he apparently went insane, climbed the roof of the school, as well as the doors of the church, and threatened the wife of a local guru with a parang.

On December 17, 1935 villagers brought him to the missionary hospital in Serui, where he was at first separated from the other patients, and put under supervision of a mantri (native medical assistant), but after an examination by Dr. Nortier, he was found to be harmless, and allowed to roam free through the hospital.

Around Christmas that year Musa fled from the institution, but was soon found at the beach of Serui and brought back. Afterwards he remained calm and helped out in the hospital, but also related to a missionary that somebody wanted to kill him.

During the night from January 18 to January 19, 1936 Musa twice left the infirmary, once at 10 p.m. and again at 5:30 a.m. At one point he grabbed a pole from the hospital's carpentry shed, and during his second leave beat to death five Papuas, as well as a man from Ternate, and wounded a seventh person.

During his examination after the attack Musa explained that he saw people while being awake, and also while sleeping, who threatend to kill him, and further related that he had been mistreated by the other patients and hospital personnel.[3][4][5]
