Do police usually find suspects?

I posted I think yesterday on here that my boyfriend and I got robbed and how much I've been traumatized now and I'm hoping they find those 3 guys. We already have the police report and the crime was first degree robbery of transportation persons inhabited. He knew one of the suspects so we already gave them his full name and the duct tape that they left in the apartment and there was also video surveillance so I'm hoping and praying to god that they catch all 3 of them 😔 I understand we're not police on here just wanna ask if any of you guys have an idea Like if they can't find them will they eventually just give up?
