The driver of a snowplow that plunged into the Platte River west of Omaha faces a child pornography charge.
Fifty-seven-year-old Scott Robertson pleaded not guilty Wednesday in U.S. District Court in Omaha.
The charge: possession of visual depictions of minors engaging in sexually explicit conduct.
U.S. marshals and Sarpy County sheriff's deputies were following the state snowplow because they thought the driver was Robertson, a wanted federal fugitive.
The plow left Nebraska Highway 31 south of Gretna and went down an embankment into the river. Officers pulled him from the water.
