[2] In 1774, Grant allegedly killed a white sea captain named Townshend and his black slave while hunting runaways near Hellshire Beach, and then fled to Moore Town for refuge.
[6] In 1781, Grant was a part of the Maroon party that successfully hunted and killed the notorious leader of a community of runaway slaves, Three Fingered Jack.
[7][8] Grant made a career hunting runaway slaves for neighbouring planters, but in 1797 he lodged a complaint about the length of time it took for the colonial authorities to pay him his rewards.
[13] In 1807, the colonial authorities exposed a slave conspiracy, and one of the informers claimed that the Charles Town Maroons were conspirators.
William Anderson Orgill, the magistrate who investigated the case, dismissed the evidence of the slave conspirators, and chose to believe Grant's expressions of loyalty.
