Omaha Police detectives continue to look into three southwest Omaha robberies, one of which included an assault, that investigators say involved a suspect armed with a hammer.
One person out for an evening walk Monday was injured in the crimes reported near 105th and Mockingbird Road, 102nd and Polk, and 90th and "L."
Police say in all three cases, witnesses and victims describe the suspect as arriving or leaving in an older silver or grey colored sedan.
The victims and witnesses also provided the same description of a suspect wearing a white Halloween mask.
Witnesses from the first incident described the mask as being a "Michael Myers" style mask.
Anyone with information can call "Omaha Crimestoppers" at 402-444 STOP.
