Sounds legit. You should have stuck with the other one. At least Florida Man reporting is open and transparent, by State Law.
Seeking out a Pro-"Palestinian" source that doesn't provide details isn't great.
After searching, here's the details I can discover:
1. This occurred in East Jerusalem. AKA held and policed by "Palestinians".
2. No suspect has been arrested.
3. No suspect has been named.
4. The "Palestinians" of East Jerusalem are known for targeting Christians equally as much as Jews.
The only indication this is Jew on Christian violence? Muslim police have told Muslim news sources that's who they think did it.
InB4 they never bag a suspect, because Muslim police in East Jeruselem don't give two shits less if Christians die. Jews either, for that matter.
In fact, the #1 thing that points to it NOT being a Jew? The fact that they haven't already been arrested, and sentenced to death.
