Two Roseburg mean have been jailed after Eugene Police and Springfield Police teamed up to catch two alleged robbers on Wednesday night, after a string of armed robberies in the Eugene and Springfield area.

A Eugene Police release said the robberies included a deli, a donut shop, a market and a pub and all took place between November 10th and November 11th.

35-year-old Gregory Todd Dennis and 39-year-old David Lee Riggleman were arrested and each charged with three counts of first-degree robbery, second-degree robbery and two counts of second-degree kidnapping. In addition, Dennis was charged with three counts of unlawful use of a weapon, being a felon in possession of a weapon and for a warrant. Riggleman was also charged with unlawful use of a weapon.

The release said Dennis is believed to have committed the robbery of the market by himself.

Both agencies worked closely together to determine the identities of the men. Springfield Police was able to identify the license plate on a surveillance camera video and conducted a detailed investigation to determine the identities of both suspects during their time in the area. Both agencies traveled to Roseburg to conduct a follow-up investigation, canvassing the area until they located the vehicle involved.

Police served search warrants on two houses, the involved car, and recovered a lot of the suspects clothing along with one firearm and two replica firearms.

Eugene Police and Springfield Police were assisted by the Roseburg Police Department and the Oregon State Police.
