Micah Johnson, the Dallas gunman who murdered five police officers and injured seven more during a Black Lives Matter protest, scrawled a message on the wall in his own blood just before dying.

Killed by a robot carrying a bomb, Johnson scribbled the letters “RB” in his own blood before he died.

While there have been several theories on the meaning of the two letters, most believe it to be an incomplete message. It is believed that Johnson was unable to finish his message, thought to be “RBG,” the initials for the popular “Red, Black, Green” of the Pan African flag, a well-known symbol of the Black Power movement.

The gunman who killed five cops in Dallas scrawled a black revolutionary message in his own blood in the seconds before he died, Daily Mail Online can reveal.

Officials say killer Micah Xavier Johnson scribbled various messages on a nearby wall during a standoff with police.

Most were illegible but the letters ‘RB’ written in blood stood out.

‘We’re trying to figure out what those initials mean,’ said Dallas Police Chief David Brown on CNN‘s ‘State of the Union.’

Daily Mail Online has now learned that Johnson possibly was trying to write ‘RBG’ – but failed to finish the last letter before he was killed.

‘RBG’ is the name given to the red, black and green Pan African flag, a powerful Black Power symbol.

Significantly, Johnson had the Pan African flag as his cover photo on Facebook and is believed to have held the symbol in high regard.

A source said: ‘There’s lots of possibilities but RBG makes the most sense given Johnson’s Black Power interests and what motivated him to carry out these attacks. Maybe he was too weak, or just didn’t get time to finish writing it.’

Johnson died when negotiations failed and police strapped a pound of C-4 explosives to a robot which was sent in to blow him up.
