One should be able to deduce that the headline would be different if he had. Therefore, one shouldn't even need to read the article to realize that one already has all of the information one needs to know the answer to this question without asking it.
Mom and daughter goes to drop off goody bag at house, does this, realizes that they dropped it off at the wrong address, goes back to pick it up, shithead point a gun at the daughter's head when they try and pick up the goody bag.
It was a 6 year old boy, also from the MSN article:
He revealed that Wen and his family were in high tension because of several incidents of home disturbances.
The family had allegedly experienced their house doors being "banged at midnight and evening."
Zou said, "His three kids were terrified and worried that somebody tried to break their door and break in." He also shared that just the night before the incident, two people had knocked on their door severally and ran away before he opened the door.
Certainly no excuse for pointing a gun but gives at least a little context to his paranoia.
