Police released sketches on Saturday of the possible suspects, or suspect, who committed two armed robberies in the University of Oregon campus area last weekend, according to the Register-Guard.

Detectives drew the sketches after speaking with both victims of the crime. In both crimes, a man approached them with a handgun and demanded their cellphones and other items that they had with them.

Police said that both victims described the robber as a black man in his 20s who wore a black sweatshirt and a black, puffy vest.

The crimes took place between 4:45 a.m. and 5:20 a.m. One of them occurred near 20th Avenue and Patterson Street, and the other occurred near a sorority house in the 800 block of East 15th Avenue.

Police ask anyone with information about the robberies to call Eugene police Detective Jed McGuire, 541-682-6308.
