A Davenport father and son and a Muscatine woman have been charged in federal court in connection with robberies at two Davenport credit unions over a seven-month period.

David Scott Denney, 33, is charged with three counts of bank robbery and one count of conspiracy to commit bank robbery. Kevin S. Denney, 59, and Cynthia Ann Niebuhr-Hartley, 31, are each charged with one count of conspiracy to commit bank robbery and bank robbery.

A preliminary hearing for all three is slated for Wednesday. The Denneys remain in custody, and Niebuhr-Hartley was released on a personal recognizance bond.

The case against the three was unsealed Friday in U.S. District Court, Davenport, according to court records.

According to the federal complaint:

On Aug. 11, a man walked into Ascentra Credit Union, 1515 W. 53rd St., presented the teller a demand note and made a verbal demand for money.

The man placed $3,930 in cash into a drawstring backpack and fled on foot to a nearby neighborhood. A witness interviewed during a neighborhood canvas said the man got into a white SUV.

Surveillance video from a nearby business also captured the vehicle, a white Dodge Durango, drive into the area shortly before the robbery and leave shortly after.

On Nov. 18, a man walked into Vibrant Credit Union, 3801 N. Brady St, presented a demand note to the teller and made off with $5,980 in cash. The man was driven to the credit union by another person in a dark-colored, first-generation Ford Escape.

He fled on foot with the money in a drawstring backpack that appeared similar to the one used in the Ascentra robbery.

On March 28, the credit union was again robbed by a man who verbally demanded all the money from the drawers of two tellers. Surveillance video showed the man driving a 1997-2003 white Dodge Durango SUV.

He made off with about $14,631 in cash from the two tellers and placed the money into a drawstring backpack.

Prior to the robbery, a witness noticed a suspicious looking man, wearing gloves and staring at the credit union, inside the white Dodge Durango in a parking lot across the street. The witness took two pictures of the vehicle.

The Dodge Durango was later located behind an apartment in the 600 block of West 63rd Street on April 3.

Police searched the apartment, which was occupied by the Denneys, and found two stacks of cash in plain view and a large wad of cash in David Denney’s pocket.

During an interview with police and the FBI, David Denney confessed that he robbed the credit unions and that Kevin Denney was the getaway driver and a knowing and willing participant in the Ascentra robbery.

He further told police that Niebuhr-Hartley drove the getaway vehicle — a blue Ford Escape — during the first Vibrant robbery and that he paid her $400 for her participation.

Kevin Denney told police that he knew his son was going to rob Ascentra and drove him there before the robbery in his Dodge Durango. He said he dropped him off across the street and drove to the neighborhood behind the credit union to wait.

He said David Denney paid him for back rent and back car payments with proceeds from the robbery.

Kevin Denney denied having advance knowledge of the two other robberies but had an idea David Denney was going to commit other robberies. He further said his son gave him money a few days after the first Vibrant robbery and he presumed the money came from robbery.

Kevin Denney said he helped his son count the money that was taken from the second Vibrant robbery and he used some of the money to pay bills.

On April 4, Niebuhr-Hartley told police that David Denney, whom she met online a couple years ago, approached her in fall 2016 and asked her to be his driver for an unspecified activity.

Niebuhr-Hartley said she eventually learned that David Denney was going to rob a bank and she was willing to participate.

She admitted that she drove him and parked at a nearby business north of Vibrant the day of the first robbery. Niebuhr-Hartley also said 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 complaint.
