PITTSBURGH (KDKA) — The Secret Service is investigating what are being described as threats against President Barack Obama.

The KDKA Investigators have learned the threats were posted online by a Pittsburgh man on Craigslist.

The photos show targets on the forehead of President Obama and other shots show the president with gunshot wounds to his head.

Other pictures show similar targets and gunshot wounds on the head of House Speaker Nancy Pelosi.

When Craigslist users saw the postings, they reached out to the Secret Service. A Secret Service memo obtained by the KDKA Investigators indicates investigators asked for help with the case stating: “You recently sent information to the U.S. Secret Service webmaster regarding threatening messages posted on Craigslist-Pittsburgh. The site has been taken down and we are unable to view the threats. Do you have a screen shot of the threats?”

Sources indicate there are thousands of death threats against the president each year. The vast majority of the threats are not credible; however, each one has to be investigated meticulously.

Meantime, sources indicate if this threat is found to be credible, the suspect in Pittsburgh will be arrested and charged under federal law.
