This bug is driving me crazy....what kind is it?

I moved into my apartment about 2 months ago..and a little over a month ago I walked into my kitchen in the morning and turned the light on..and was face to face with some sort of bug. I was horrified but didn't know what to do it ran under my counter top. I thought it was odd considering I don't leave food out and take the trash out regularly and don't have the environment id figure would attract a bug. Then today I saw it again. Its only the second time I've seen it but it was across my counter so I had time to kill it this time. I'm hoping its over but I can't figure out what kind of bug it is. I thought it was a cockroach but it doesn't have an antenae or anything. its just a little brown beetle looking thing not tiny but not big. any ideas? if I see more should I inform my complex manager for them to take care of it, or should I do it myself?
