I’ve found obits at, at (drill down to the state and county and see what they’ve got listed — if not listed, look for Look-Up volunteers on the pages for that county and request help), on local historical society websites, on family websites and forums (try and search or post a query under the surname and/or location you’re looking for), etc.

I’ve even done some creative Googling to find out if the obit is online, such as:
“smith, jane” topeka obit
“jane smith” topeka
“smith, jane” shawnee county
“jane smith” kansas
“smith, jane” obit [i use "obit" to catch obituary, obituaries, obits, etc.]
“smith jane” death topeka

I hope this gives you some new paths to try, good luck!
