In 1841, Wathaurong man Bonjon (or "Bon Jon") was charged with murder for killing Yammowing of the Gulidjan people whose territory bordered that of the Wathaurong. According to the Wesleyan missionary Francis Tuckfield, one of the witnesses in the case, Bonjon had been in contact with Europeans more than any other member of the Wathaurong, having even been a volunteer member of the Native Police for some time. According to police magistrate Foster Fyans, Bonjon was with the Native Police for seven months, tracking runaway horses and generally assisting the other members. The prosecution alleged that on or about 14 July 1841, Bonjon shot Yammowing in the head with a carbine at Geelong, killing him.
