Eugene, OR – Two men from Roseburg were arrested after Eugene and Springfield police worked together to investigate a series of armed robberies targeting businesses in the Eugene and Springfield area.

Gregory Todd Dennis, 35, and David Lee Riggleman, 39, were taken into custody Wednesday night in Roseburg and lodged at the Lane County Jail.

Police said the robberies included Anna’s Deli on Royal Avenue and Dizzy Jean Donuts on Pioneer Parkway East on November 10, Hilltop Market on Donald Street on November 6, and Mulligan’s Pub on Willamette Street on September 11.

Dennis faces three counts of first-degree robbery, one count of second-degree robbery, two counts of second-degree kidnapping, three counts of unlawful use of a weapon, possession of a firearm by a felon and an outstanding warrant. Riggleman faces two counts of first-degree robbery, one count of second-degree robbery, two counts of second-degree kidnapping and unlawful use of a weapon.

Investigators believe Dennis carried out the Hilltop Market robbery alone.

According to police, Springfield officers identified a license plate captured on surveillance video and conducted an investigation that helped identify both suspects. Officers from both agencies traveled to Roseburg to continue the investigation and located the vehicle believed to be involved.

Police served search warrants at two residences and on the vehicle, recovering clothing believed to be connected to the robberies, one firearm and two replica firearms.

Eugene and Springfield police also thanked the Roseburg Police Department for its assistance, along with Oregon State Police, which provided a K9 officer during the investigation at the deli robbery scene.
