What will happen to my neighbours dog?

my neighbours mastiff dog escaped and attacked and killed my Jack russell, my three yr old son saw it happen and is terrified. the court put a control order on the dog saying that it had to be muzzled at all times outside and on a lead, less than a week after the control order was issued the dog escaped and was wandering the streets barking at people. what will happen to the dog now? will they give my neighbours another chance? my 3 yr old son is terrified of all dogs and wakes up screaming every night, we never asked for the dog to be put down, we just didnt want it back next door after what it did, the police have seized the dog and the owners are having to go back to court
