Two Roseburg men are in the Lane County Jail after police connected them to armed robberies at Eugene and Springfield businesses, including a Springfield donut shop and an Eugene deli on the morning of Nov. 10.
Investigators treated those calls as part of a longer series. KATU reported that Springfield officers responded on the morning of Nov. 10 to an armed robbery that had just occurred at Bizzy Jean's Donuts, 1811 Pioneer Parkway East, and that Eugene officers went to Anna's Deli, 4716 Royal Ave., at about 8:21 a.m.
Two Morning Calls
Police suspected the same two people in both of those robberies, KATU reported. The shops are in different cities, and the second call came roughly two hours after the first.
Springfield police identified a license plate on surveillance video, then worked with Eugene police to canvass the area until they located the vehicle involved, according to an account from KQEN News Radio. That plate became the thread between the two morning reports.
Earlier Eugene Robberies
The Nov. 10 robberies were not the start of the case. Lookout Eugene-Springfield reported that police said they linked Gregory Todd Dennis to a Sept. 11 robbery of Mulligan's Pub and a Nov. 6 robbery of Hilltop Market, both in Eugene.
An Eugene police release said Dennis is believed to have committed the market robbery alone. Lookout reported that David Lee Riggleman is suspected of taking part in three of the robberies, but not the Hilltop Market robbery. Police are not describing the two men as partners in every incident.
How the Case Moved to Roseburg
Springfield police said detectives used physical evidence, surveillance footage, witness interviews and suspect interviews, and developed probable cause to arrest Dennis for the armed robbery and two other Eugene robberies. Lookout reported that Riggleman was identified through surveillance video, interviews and physical evidence.
Eugene and Springfield investigators then traveled to Roseburg for follow-up work, with help from the Roseburg Police Department and Oregon State Police, according to the KQEN account. Police served search warrants on two houses and the involved car.
From those searches, police recovered the suspects' clothing, one firearm and two replica firearms.
Lane County Jail and Court
Both men were arrested in Douglas County and taken to the Lane County Jail, KATU reported. Dennis, 35, and Riggleman, 39, both of Roseburg, have been charged in Lane County Circuit Court with multiple counts of robbery and unlawful use of a weapon, among other charges, Lookout reported.
Those are allegations pending in circuit court. Which robbery is tied to which man is now a question for that case, not for the police narrative alone.
