I agree.  To me it sounds like your child has been kidnapped, literally, and under the "watchful eye" of the police.  In most states, for a noncustodial parent to just snatch up a child, it can be considered kidnapping.  "Parental kidnapping or parental abduction is defined as the concealment, taking, or retention of a child by his parent in violation of the rights of the child's other parent or another family member. Violated rights may include, for example, custody and visitation rights."  But it can get a little more complicated than that, so it is wise you already have your attorney looking into it.

Here is a link to an article I found.  This article also adds that the police usually consider such a civil matter and not a criminal matter; however, I'm pretty sure if it was a bio-dad trying to take a child away from a BM, the police would have responded much differently.  https://wehavekids.com/parenting/My-Ex-Wont-Return-My-Kids-Child-Custody...

This is a concise well-written article that was written by someone who went through it.  Best of luck to you!!

Here is a link to what the FBI has to say about it: https://leb.fbi.gov/articles/featured-articles/domestic-custodial-motiva...

However, the article states, "The prompt reporting of the kidnapping by the custodial parent to officers and the timeliness of law enforcement personnel in responding to a child abducted by a noncustodial parent prove crucial in increasing the likelihood of recovering the child unharmed and apprehending the offender.  When a custodial-motivated child abduction is reported to law enforcement, the child should be considered in danger. . . ."  A heck of a lot good that did you!, going to the cops.  I hope your lawyer in addition to getting your child back for your DH and you, makes the cops who looked the other way on this feel like they did something wrong--because they did.  Maybe not legally wrong, but ethically wrong.  My guess is they saw a BM in tears and thought nothing of looking the other way, or making your DH and you feel like you were the ones doing something wrong.

This article goes on to say, "The timely response of law enforcement, rarely the willingness of the parent to return the child, results in the recovery of the children."  Sure didn't happen to you.  I'd for sure go back to the local, or better yet, county police station and ask someone in charge what they are going to do about this.  Ask them too why the initial cops responded the way they did.

So glad you were able to get your DH's and your child back!  Keep good notes, and don't hesitate to get a restraining order on whomever is threatening you.  It may take a while, even tho. it should not, but keep documenting threats, even so-called thinly veiled ones and requesting.  Hoping it'll start to calm down after fake G-pa feels like he has fluffed his feathers a time or two in front of BM over this.  Apparently he wants to "impress" her.  (Are fake G-pa and BM having a thing!?  Wouldn't doubt it.)

Unfortunately, sometimes cops get lazy, just like paid employees can in any profession.  And, they do hate to get involved in what they see as civil suits (vs. criminal), but that is no excuse, really.  The law is the law and they are supposed to enforce it.  As you've seen, that is why you have to go through the judicial system sometimes (as you will do with a restraining order) to get them to properly do their jobs.

It is great to hear of a potentially tragic blended family situation evolve as a win for the good guys!

Take care of that baby and your family.

Tolerate no crap from that sickening shallow and polluted gene pool on the side of the blended family opposition.
