Permanently deleting alias files?

Hey there,

A while ago I deleted some pics from my iMac. just a short time ago I noticed that these photos showed up when I searched via ALL MY FILES in the finder. They appear to be dead alias files. If I click on one it is just a page file, no preview picture and no file extension/file path shows up at all. if I try to quick look it, it comes up blank.

If I double click it I get a "the alias **** can't be opened because the original item can't be found. DELETE ALIAS, FIX ALIAS…, OK
delete alias does nothing, fix alias holds no help. I can't drag the file anywhere. If I use the little gear along the top of the finder to GET INFO it gives me sparse info and a shaded out name on the file. sharing and permissions says "you have unknown access" with no option to change anything.

I have tried restarting my computer, option-command-esc and restart finder. but nothing lets me delete these blank pic files. WTH? any ideas here? as I look through my files trying to manually find where these alias files might be hidden I notice I have a good number of these dead alias files for other stuff I have deleted and supposedly purged from my computer so any way to actually delete this stuff completely would be greatly appreciated.
