Try these in Google, but since you don't give much details I don't know what other terms or words are similar to "category manager" - Please add those to this string to produce more results. Also feel free to add the area codes and/or zip codes or just do (minnesota | mn) and take out minneapolis/st paul to get more:
(inurl:resume | intitle:resume) "category manager" (minneapolis | "st paul") (mn | minnesota) -apply -job -jobs -sample -submit
I realize you tried linkedin, however try this string as it brought back 'many' results in Google:
site:linkedin.com "category manager" "Greater Minneapolis-St. Paul Area" (inurl:pub | inurl:in) -intitle:directory
You could also insert "current * category manager" instead of just "category manager" to get current titles.
