How to contact the NJ police online?

So my bf is being stalked by some girl he doesnt know and she is hacking accounts and saying he is her boyfriend. She even hacked his phone so she can see who is texting him. He wont call the cops and I feel like he should. I live in Washington and he is in NJ. I tried going to the NJ police site, but couldnt find any way of contacting them about an emergency. How do i get a hold of them?
