An Urbandale man is charged with first-degree murder in the Nov. 2 killings.

BISMARCK, N.D. (AP) — North Dakota regulators are proposing a fine of at least $15,000 against the company building the four-state Dakota Access pipeline. The Public Service Commission said Monday in a complaint that a subsidiary of Texas-based Energy Transfer Partners didn’t get regulators’ approval to proceed with construction after artifacts were found last month. The company diverted construction and said in a statement that the company doesn’t think it did anything wrong and is working with the PSC.

WATERLOO, Iowa (AP) — Black Hawk County officials will pay $30,000 to a man who scuffled with an off-duty sheriff’s deputy after a traffic dispute. The Waterloo-Cedar Falls Courier reports the Board of Supervisors voted Tuesday to pay the money and settle a case filed by Edward Felts. He claimed deputy Richard Hoffman beat him during a 2015 incident, which happened after the men nearly crashed while driving. The men exited their vehicles, and after Felts head-butted Hoffman, the deputy took Felts to the ground.
