(CNN) -- One of the Oklahoma teenagers accused of killing 23-year-old Australian Christopher Lane had previously posted images online showing himself posing with guns and wads of cash.
And three days before what police call the indiscriminate shooting, the suspect, 15-year-old James Edwards Jr., tweeted, "With my n****s when it's time to start taken life's."
Back in April, he tweeted, "90% of white ppl (people) are nasty. #HATE THEM."
Police in the town of Duncan have charged Edwards and Chancey Luna, 16, as adults with first degree felony murder, said Kaylee Chandler, a Stephens County court clerk.
Michael Jones, their alleged 17-year-old driver, faces two charges: use of a vehicle in the discharge of a weapon and accessory after the fact to murder in the first degree.
A judge set bond at $1 million for Jones, while no bond was set for Edwards and Luna, Chandler said.
Police say it was Jones who ultimately told them, "We were bored and didn't have anything to do, so we decided to kill somebody."
The police affidavit lists Edwards and Chancey as black, and Jones as white.
