They, along with crime analysts, have noted similarities indicating the same two suspects could be responsible for several crimes across Raleigh.
The robberies have been happening since the beginning of October, with the most recent one taking place last weekend.
Saturday, police were called to two robberies. The first happened just after midnight at the Circle K store in the 3600 block of Lake Boone Trail. Hours later around 7:30 p.m., the Roma's Pizzeria in the 3800 block of Brentwood Road was robbed at gunpoint.
Other crimes include robbery at; Papa John's on Capital Blvd. on Oct. 26, Peace Street Market on Peace Street on Halloween night, Circle K on Spring Forest Road on Nov. 6, Domino's Pizza on Falls Of Neuse Road on Nov. 6 and Sophie's Deli on Integrity Drive on Nov. 8. There was also an attempted robbery at the Exxon on New Bern Avenue on Nov. 6.
Two suspects have been involved in all but one of the cases. Only one suspect was seen during the Nov. 8 robbery.
Raleigh Police Department Director of Public Affairs Jim Sughrue said the suspects have been described as African American men who stand about 6 feet tall. He also said they usually disguise their identities with bandanas.
"In most instances, the weight of one of them has been estimated at 200-240 pounds," he said in a news release. "Bulky jackets have made it difficult for some victims to determine body types. It's possible the second suspect may weigh approximately 170-180 pounds."
Surveillance video from one of the crimes showed one of the suspects wearing a distinctive blue jacket, which has been identified as an NBA "throwback" jacket with the logo for the Syracuse Nationals on the back. The jacket appeared to have the number "1949" on the left sleeve and "NBA" on the right sleeve. The suspect was wearing dark colored jeans and dark colored Converse Chuck Taylor-style high-top shoes with white trim.
The other suspect was seen wearing a heavy black jacket and dark colored pants.
Police said the pair used a combination of long guns and handguns during the crimes.
