KANSAS CITY, Mo. • Federal prosecutors have charged a 42-year-old Columbia, Missouri, man with trying to burn down a Planned Parenthood clinic last month.

Prosecutors announced Monday that Wesley Brian Kaster was arrested Saturday on a charge pertaining to the pre-dawn Feb. 10 fire at the Planned Parenthood-Columbia Health Center, which was empty at the time.

Kaster faces a preliminary charge of using fire or an explosive to maliciously damage a building that receives federal funding, but that could change. The FBI had said it was investigating the attack as a possible hate crime.

"All I can say at this point is that it is an ongoing investigation and we are early in the process," Don Ledford, a spokesman for the U.S. Attorney's office, said Monday. "A complaint is a temporary charge; this case will be presented to a federal grand jury in the near future, which could return an indictment with different or additional charges."
