Ever since the silent catches were added in the summer update when you try to kill a kid as neighbor they take 1 second longer to kill then normal. If I'm right the kids are only supposed to die slower on the silent catches however the bug makes it so that kids die slower even on a normal catch. This big has caused many unfortunate scenarios where the neighbor could have killed a kid but they were saved at the last second.
(This may have already been reported but I don't remember seeing this. Let me know if this is working as intended, but it definitely feels more like a bug since it never mentioned this in the patch notes and the feedback post that suggested the silent catches said to make silent kills only last longer, not normal kills)

Hey, thank you for letting us know of this! 
There could be a chance that if you shot her with a rifle she would have 1 life left.
?
I'm talking about the toy rifle
There was a bug or something like that, the rifle shot left 1 HP left
It happened more with the neighbor
Oh, well that's the rifle, I'm talking about killing kids.
If you have any details about it you can report the rifle bug in a bug report
