Police released several pictures of a wooden cross and asked the public for information about anyone seen with such cross or business that sells it.
On Friday police did not say where the 1-1/2 inch-by-1-inch cross with an offset horizontal bar was found - or why it might be associated with the case.
The cross has a hole drilled through the upper part and could be worn on a necklace.
On one side of the cross are three vertical bars etched onto the shorter horizontal section and a zig-zag pattern is carved onto the opposite side.
For most of the investigation, Ridgeway's great-grandmother Donna Moss has had to follow developments from her home in Missouri.
Saturday she said she had a "gut feeling" investigators were about to crack the case.
"I know there's got to be people out there who know who wore that cross," Moss said. "And I'm hoping that someone out there that knows who wore that cross will be brave enough to say 'well at least check with this person.'"
Former FBI profiler Clint Van Zandt says investigators rarely give the public a glimpse into the evidence they have unless they absolutely need to.
"The police [and] the FBI may have someone under surveillance right now and all they need to do is link this one current piece of evidence," he said. "That could give them enough to go forward with search warrants, arrest warrants, etc."
Police believe there may be a connection between the Ridgeway murder and the attempted Memorial Day abduction at Ketner Lake.
They urge the public to specifically look for someone with a similar cross - that matches the suspect's description from Ketner Lake:
• Light skinned male
• 18-35 (or someone who's appearance with a ball cap may look that age)
• Brown hair
• Medium build
• 5'06" to 5'08" (Height can vary above or below these approximations)
Police are asking the community to look through the pictures and call the tip line or send them an email with information that may identify the killer or where he may have gotten the cross from. Tip line: 303-658-4336 email: PDamberalert@cityofwestminster.us
