Pair arrested in connection with armed robberies of businesses in Springfield, Eugene

Two men arrested Wednesday, Nov. 11, in Douglas County are suspects in a string of armed robberies at businesses including a Springfield doughnut shop and a Eugene bar.

Gregory Todd Dennis, 35, and David Lee 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.

Springfield police said they responded at 6:25 a.m. Tuesday to a report of an armed robbery at Bizzy Jean’s Donuts on the 1800 block of Pioneer Parkway East. No suspects were at the business when police arrived, but two men reportedly dressed all in black had robbed the doughnut shop employee and taken cash.

Less than two hours later, Eugene police responded to Anna’s Deli on the 4700 block of Royal Avenue for another report of an armed robbery.

Based on evidence including surveillance video, Springfield police identified a vehicle believed to have been used by the suspects. Police from both agencies working together identified Dennis as a suspect.

After arresting Dennis during a Roseburg traffic stop, police said they linked him to a Sept. 11 robbery of Mulligan’s Pub and a Nov. 6 robbery of Hilltop Market, both in Eugene.

Riggleman was identified through a combination of surveillance video, witness and suspect interviews and physical evidence, Springfield police said. He was arrested in a rural area of Douglas County and is suspected of participating in three of the robberies but not the Hilltop Market robbery.
