The man charged with planting a bomb along the route of the Martin Luther King Jr. Day parade in Spokane is pleading not guilty to the four charges against him, including a hate crimes charge.

Kevin Harpham entered the pleas Monday before U.S. Magistrate Cynthia Imbrogno. He remains without bail in the Spokane County Jail.

Up until last week Harpham had been charged with attempting to use a weapon of mass destruction and possessing an unregistered explosive. Then last week a grand jury indicted him with a hate crime and using an explosive to commit a hate crime.

The superseding indictment alleges the attempted bombing back on January 17 targeted minorities and was racially motivated. Harpham is now accused of violating the Federal Hate Crimes Act and using an explosive to commit a hate crime.

In court Monday Harpham learned if he was convicted in court on the new charges he faces a minimum of 30 years in prison with no time off for good behavior. It means that Harpham if convicted could be at least 66 years old before he could be released from prison.

"Yeah that's serious, you cannot be convicted of that alone. You have to be convicted of that hate crime to be convicted of count four. Without a conviction of a hate crime count four disappears," Harpham's federal public defender, Roger Peven, said.

In an effort to prove Harpham was motivated by hate it appears his mother and father testified before the grand jury last week. The US Attorney may have been using Harpham's parents to demonstrate to jurors Harpham's long history of prejudice against minorities.

His trial is scheduled to get underway on May 31.
