Did you remove the photos from the LR catalog, only, or did you Delete from disk as well? In other words are the files still on your hard-drive, just not imported into LR anymore or are they gone from your hard drive, too?
When i uploaded them, I uploaded them directly to LR. So I'm not sure if they get saved elsewhere on my laptop when I do that. I have a mac also.
Photos are not stored inside of LR. The LR catalog contains records of the locations of the photos when you imported them and any settings/keywords/etc you apply to the photos after import.
When you import into LR, the destination is specified at the upper-right of the Import panel. When you import from a camera memory card or from a camera connected to the computer, LR first copies the photos to the destination specified in the Import panel then it Imports the photos--records their location and builds thumbnails.
When you remove a photo, you remove the record of where the photo is located and any settings/keywords/etc applied to that photo. As part of the removal process you are asked a question, whether to also delete the photo from the hard-drive or only to remove the LR records associated with the photo, which was my first question, earlier.
Something more important is where does LR copy the photos just in case you didn't delete them and only removed record of them in LR. I would suggest you right-click on one of the other imported photos and choose Reveal in Explorer/Finder and see where that photo is stored, then click around to other parent and child folders of that location and see if you can find the other photos you removed, to see if they were also deleted.
Also, if you haven't taken any more photos or otherwise stored new data on the memory card, there are utilities you can download that can recover photos from a memory card, although they work better with JPGs than with raw files. Usually a recovery utility will scan the card and show you thumbnails of what photos it finds, and then you have to pay for an activation code to actually have it recover the photos.
In other words, figure out where the photos were stored to see if they are still there, and if not then try undeleting them from the camera memory card.
Like ssprengel says. Also, if you deleted them from disk, they may still be in the recycle bin, so don't empty the trash.
