The Twitter and Facebook accounts of one of three Oklahoma teens accused of shooting a jogger to death for sport, is peppered with graphic language about hating — and killing — white people.

Fifteen-year-old James Edwards and two other teens have been charged with first degree murder in the slaying of Christopher Lane, 22, an Australian who was in the United States on a baseball scholarship.

Chancey Luna, 16, has also been charged with first degree murder. Micheal Jones, 17, has been charged with accessory to first-degree murder after the fact, according to news reports.

Edwards’ Twitter account @jamesakabug contains graphic language about his dislike of “nasty white people.” On April 29, he tweeted, “90% of white ppl are nasty. #HATE THEM.”

Edwards' Twitter and Facebook posts show him glorifying hip-hop, racism, violence against women and drugs. Pictures on Facebook also show Edwards and Luna wearing gang colors and flashing gang signs, according to a report in dailycaller.com.

Police say the three teens decided to shoot Lane, 22, because they were bored.

The teens followed Lane as he jogged, shot him in the back and left him to die on the side of a road, according to police. “They were bored and just wanted to see somebody die,” Duncan police chief Danny Ford told ABCNews.com. Police said a woman called 911 after seeing the dying man stagger across a road and collapse.

Lane, who was in the United States on a baseball scholarship at the school in Ada, Okla. was visiting his girlfriend in Duncan, when the shooting occurred, according to news reports.

Lane’s girlfriend, Sarah Harper, told the Australian Broadcasting Corp.: “He didn’t deserve any of this. It’s heartbreaking that it was such a random choice those guys made that drastically altered so many lives in the process.”

On the heels of the death of Lane in Oklahoma comes another incident involving teenagers in Spokane, Wash.

Two teens allegedly beat and left for dead a WWII veteran, according to an Associated Press report and a story on kxly.com. Delbert Belton, 88, survived being wounded in action during the Battle of Okinawa, only to die Thursday after the alleged beating by the teens on Wednesday evening, according to the report. Authorities said the beating appeared random.
