Federal charges filed in Fort Riley case

A South Dakota man has been charged with entering Fort Riley with the intent to kill a man, federal authorities said.

Ryan Peterson of Ipswich has been charged in federal court with one count of attempted murder, one count of attempted aggravated burglary, two counts of criminal trespass on a federal military post and one count of criminal damage to property.

Prosecutors allege that Peterson drove from Ipswich to Fort Riley on May 22, armed with a hunting knife and a painter's tool, intent on breaking into the victim's quarters.

The indictment alleges Peterson told police after his arrest that he had intended to kill the victim by sneaking up behind him and cutting his throat. Peterson attempted to break in.

He then rang the doorbell, confronted the victim and ran away. He hid in nearby trees and once again tried to break into the house while the victim was inside, the indictment states. He was arrested by Fort Riley police outside the house.

Peterson is also accused of cutting the tires of the victim's 2007 Ford Focus and 2008 Dodge Caliber autos on Feb. 28.

If he is convicted, Peterson faces 20 years in prison and a fine of up to $250,000 for attempted murder; one year in prison and a $100,000 fine on attempted aggravated burglary; six months in prison and a $5,000 fine on criminal trespass; and seven months and a $1,000 fine on criminal damage to property.
