ST. PAUL, Minn. - Graffiti can sometimes grab the attention of those passing by, but rarely can it lead to a federal investigation, which is the result of some vandalism on Lake Como in St. Paul.

At about 6 a.m. Sunday morning, someone noticed racist graffiti at a fishing dock along Lake Como in St. Paul. The graffiti includes racial slurs targeting African Americans, as well as the phrase "Kill Obama."

St. Paul police have covered five locations of graffiti along the dock with tape as the investigation continues. Police said the graffiti happened overnight Saturday and was isolated to the dock.

Police have no surveillance video of the incident and have no suspects.

"It's does not surprise me that it happened at all, and it doesn't surprise me it happened at Como Park," Lucky Rosenbloom, of the Council on black Minnesotans, said. "Ugliness can rear its head anywhere."

Rosenbloom believes Obama's presidency gives "closet racists" a change to act out.

"The longer we see Obama in office, we're going to see this come up over and over again," he said. "This is not the last time."

The graffiti would be considered property damage and a hate crime. Since it included a threat to the president's life, it is a federal offense and the U.S. Secret Service has been notified.
