CEDAR RAPIDS, Iowa (AP) — A Waterloo man has been sentenced to two years in federal prison for threatening to kill his ex-girlfriend. Federal prosecutors in Iowa say 25-year-old Adam Charles Butler was sentenced Thursday after he pleaded guilty in November to willfully making threats to kill or injure another by means of an explosive.

Investigators say Butler has a lengthy history of domestic violence, including physical assaults, break-ins, vandalism, threats with guns and repeated verbal and text message death threats. At Butler’s sentencing, prosecutors referenced text messages Butler sent to his ex-girlfriend threatening to blow up her car and apartment while she and their young child were at home.

Officers arrested Butler after seeing him driving away from the woman’s home in violation of a no-contact order.

FORT MADISON, Iowa (AP) — Amtrak trains will still stop in Fort Madison but passengers will no longer be able to buy tickets at the depot counter as the carrier moves toward digital-only sales. The railway is transitioning 18 stations to be digital-only this year, The Hawk Eye reported .

Passengers are encouraged to purchase tickets online, through a mobile app or by calling Amtrak. Passengers can also pay in cash on the train, but will be charged higher prices and be subject to availability.

The company decided to make the switch because figures show that ticket counters account for fewer than 5 percent of ticket sales nationally, said Marc Magliari, a spokesman for Amtrak. “The volume of people who are using the ticket counter in Fort Madison and other places has fallen off pretty steeply,” Magliari said. “And that is not a reflection of the quality of work of the ticket agents.”

Checked baggage will also no longer be available at the Fort Madison station. Customers who need full customer service can use the Galesburg station, which is about an hour and a half northeast of Fort Madison, Magliari said. Fort Madison Mayor Brad Randolph said some residents expressed concerns about needing assistance and not having a person at the ticket window. He said the company may consider adding the position back if it sees a significant drop in customer satisfaction.

Company spokesman Ray Lang said getting rid of the station’s ticket agent isn’t a sign that the company will halt services altogether at the Fort Madison station.

DES MOINES, Iowa (AP) — An Iowa teen has been given a suspended prison sentence and probation for torching a famed covered bridge in Madison County, Iowa, that featured on the cover of the novel “The Bridges of Madison County.”

Television station KCCI reports that 18-year-old Alexander Hoff was sentenced Friday, getting five years’ probation and a suspended 10-year prison sentence. He had pleaded guilty in March to second-degree arson and first-degree criminal mischief.

Hoff was among three people who set fire to the bridge in April 2017. The two others — Joel Davis and Alivia Bergmann — were sentenced to five years’ probation. The bridge near Winterset also was featured in the 1995 movie adaptation of “The Bridges of Madison County.”
