he opened the door?
WTF?
Yup, before, the story was that she greeted him at the door when she opened it.
We get 911 calls all the time, we open the door to look for a patient. Usually we find one who cannot get to a door. Sometimes we send the police in first. Depends on the neighborhood. In my state a group of EMS providers went into a residence met the patient, he requested a minute to get something in the other room, it was granted, he came out with a gun shooting at them....they ran for their lives. One was dead afterwards. Believe me, EMS and police do NOT want to open a door and walk in to an ambush, but it is the job.
