In December of 2009 my boyfriend had a warrant for his arrest for not paying his past due child support. He does spend time with me in my home-but my home is not his address. Two county sheriffs came to my house and one of them put a patio chair under my kitchen window--entered my house--let the other sheriff in through the front door and then they proceeded to search the house-looking for my boyfriend. They unlocked my children's bedroom doors and left a closet door in my spare bedroom open. They came in my bedroom and found my boyfriend in the bathroom. All the while-I had no idea all this was going on. My doctor has me on medication for depression and anxiety. Needless to say, the medication puts me into a very deep sleep. Which was what I was doing when the sheriff broke into my home. This ordeal has really stressed me out. Did they (sheriffs) have the right (legally) to do what they did without my permission to enter or without a search warrant? I really need to know.
In some states an arrest warrant gives law enforcement the authority to enter a residence where he might be staying. It is also possible that while YOU may not consider your home his residence, it is possible that HE has been using your home address as his residence. if so, and they had good cause to believe he was home, then they almost certainly had reason to access the home.
The usual remedy for a bad search is the suppression of evidence. If no evidence of an additional crime was located, there is no easy venue for a remedy. You can always hire an attorney and sue the sheriff's office and hope that a jury will find your damages sufficient for an award to cover attorney's fees, but without any actual damages this is unlikely.
You can also make a complaint to the sheriff's office and have them look into the actions of their people.
Of course, you might also find child services at your doorstep asking you why you are concealing a fugitive in your residence and around your children.
How much of a stink you want to raise is up to you. But, unless you or he are facing new charges as a result of the entry, there may be little you can do aside from complaining to the sheriff's department.
Oh, and even if they DID make an unlawful entry, your boyfriend does no get to go free and avoid the charges - the matters would be separate issues and would not change his predicament in the slightest.
