Parasteatoda tepidariorum or Steatoda borealis. It is killing a stinkbug that walked into its web. The stinkbug died very quickly. It had gold markings that looked like S. borealis though the spider looks different in this anterior view. This was the clearest photo. A house centipede was nearby watching the predation appearing ready to grab either the spider or insect if they left the web.
