A Davenport father and son have pleaded guilty to charges in connection with several bank robberies in 2016 and earlier this year.

David S. Denney, 33, pleaded guilty Friday in U.S. District Court, Davenport, to three counts of bank robbery and one count of conspiracy to commit bank robbery. He will be sentenced March 20, according to court records.

Kevin S. Denney, 59, pleaded guilty the same day to one count each of conspiracy to commit bank robbery and bank robbery. He will be sentenced March 19, according to court records.

Their co-defendant, Cynthia Niebuhr-Hartley, 32, of Muscatine, pleaded guilty Nov. 14 to bank robbery and conspiracy to commit bank robbery. She also will be sentenced March 19.

According to court documents:

David Denney is accused of robbing Ascentra Credit Union, 1515 W. 53rd St., on Aug. 11, 2016, stealing $3,930 in cash; robbing the Vibrant Credit Union, 3801 N. Brady St, on Nov. 18, 2016, and making off with $5,980 in cash; and robbing the Vibrant Credit Union again March 30, stealing $14,631 from two tellers. During an interview with police and the FBI, David Denney confessed he robbed the credit unions and that his father, Kevin Denney, was the getaway driver and a knowing and willing participant in the Ascentra robbery, and that Niebuhr-Hartley drove the getaway vehicle during the first Vibrant robbery and that he paid her $400 for her participation.

Niebuhr-Hartley told police she was involved in the planning of the second Vibrant robbery and agreed to be the getaway driver for 25 percent of the robbery proceeds. The two tried to coordinate a date for the robbery but were unsuccessful.

Niebuhr-Hartley said she learned that the credit union was robbed when she received a news alert on her cellphone. She said she knew it had to be David Denney and was angry that she did not get to participate, according to the court documents.
