Richard Johnson was a Texas cowboy who went with the Lee faction during the Lee-Peacock Feud in Grayson Co. during the 1860's. When Bob Lee, the leader of the Lees, was killed in June 1869, Johnson headed to west Texas to raise cattle. When the Peacocks killed a half-brother in 1871, Johnson came back to Grayson Co. to avenge the death.
Together with Joe Parker, Johnson went to the leader of the Peacock's ranch and laid in wait up in a tree for the owner, Lewis Peacock, to appear. As Peacock stepped outside and stood on his front porch, Johnson fired, killing Peacock instantly with a bullet to the heart. Johnson fled and was never caught. The Lee-Peacock Feud ended abruptly following Lewis Peacock's death.
