Roo,
I am glad you put a stop to this. My step-son was murdered 8 years ago
@ his cousins house by the cousins roommate. This was the 1st time my step-son met this man. They got into a fight in the house and instead of the cousin putting a stop to it, he told them to take it outside. Less than an hour later my step-son was dead. He was beat to death.

This kind of thing could have happened at your place evidentally. You certainly wouldn't have wanted this to happen and trigger PTSD again. Just keep youe eyes and ears open for awhile even after they move.
Take care,
