Per sources - homeowner (wife) was home alone - husband is out of town. Her alarm company called her to tell her back door had been opened -she heard activity downstairs and ran to her neighbors' house. According to the neighbor it was more than 1 intruder but Chief only mentions one.
Looks like they recoevered shell casings inside the house, presumably from the intruders shooting at the cops.
