CHARLEY O ELDRIDGE 1502 UPLAND AVE BOULDER, CO 80302
You can't find Charley on Upland anymore because it looks like he sold the house in 1994. On ICRIS you can see that the deed went from Charley to Charley, Jr., and then to a real estate partnership. That transaction matches the time of this death from the SSDI:

Maybe this is the son:
