Domestic Violence Help

My ex boyfriend beat me up stole my car and twisted my shoulder out of the socket a couple of months ago. He went to jail but they could only hold him for 12 hours. He missed the court date and now he has a warrant out for his arrest and a $303.00 fine. Recently he posted on Facebook mocking beating and abusing women. I want him behind bars. And I know where he lives. Is there anyway I can alert the police of his whereabouts?
