PITTSBURGH -- The Anti-Defamation League said the suspect in the shooting deaths of three Pittsburgh police officers made a blog entry on a white supremacist Web site just three hours before the slayings.

Richard Poplawski is accused in the shooting deaths of Pittsburgh police officers, Eric Kelly, Paul Sciullo and Stephen Mayhle. The three officers were killed Saturday morning when they responded to a domestic disturbance call at Poplawski's home.

Internet rantings by Poplawski were found on the white supremacist Web site, Stormfront.org. They show that he was preoccupied with the idea that Obama was going to overturn the Second Amendment and that Jews were secretly running the country.

Steve Irwin, with the Anti-Defamation League, monitors "hate" Web sites like Stormfront.org. Irwin and the ADL examined Poplawski's Internet use after his arrest.

Poplawski posted a shirtless picture of himself, showing off a large tattoo of a spread-winged eagle below his collarbone. The ADL said it is a marking that's often a tribute to Hitler and the Nazi party.

As Poplawski blogged over the years, the ADL said his postings became more disturbing as they indicated a desire to be confrontational.

The ADL said he wanted to achieve ultimate victory for his people by taking back the nation and ramping up the activism.

Friends said Poplawski was upset and angry about losing his job a few months ago, feared that President Barack Obama would take away his gun rights, and believed Jews controlled the news media.

Edward Perkovic, a friend of Poplawski's, said he received a call from him minutes before the slayings.

“He called me up at about eight-thirty or nine o’ clock in the morning and said, ‘Eddie, I’m gonna die today.’ I heard gunshots in the background,” Perkovic said.

He said Poplawski was worried about Zionist control of the government and that weapons would be banned.

During the battle with police, Poplawski was wearing a bulletproof vest and was armed with a variety of weapons, including an AK-47 assault rifle, authorities said.

His friends, who had been to a bar with him three days before the shootings, said he was not acting unusual. But some said he was upset about being laid off from a job at a glass factory and preoccupied by what he feared would be new restrictions on gun ownership.

One of his friends, Aaron Vire, who is black, said he did not believe Poplawski was racist.

Friends had said Poplawski had been booted out of Marine boot camp for throwing a lunch tray at a drill sergeant.

The Marines confirmed he was discharged from boot camp in Parris Island, S.C., in 2004, but said they could not disclose details because of privacy laws.
