Unknown Spotting ( Spider )

I went into the garage, at 2:00 p.m. in the afternoon. There was another, larger spider, in the same spiders web, that I saw at 5:00 a.m. in the morning. The smaller spider and its prey, were gone. This larger spider, is now resting on the same spiders web, that was once occupied by the smaller spider, and its prey. The larger spider, is about two or three times larger, than the smaller spider. The larger spider, is dark brown and medium brown, in color.
