Hard to say now, but it seems they would have mentioned this at the presser. They also would have filed kidnapping charges, too.
I also think that they only sent teams of 2 or so people in most of the homes, but I think all 4 of them went to DR's trailer. It was the only home where there were 3 different people asleep in three different bedrooms in the same home. They would have needed people in various rooms to make sure no one escaped before all were killed. There was an exit at the back of DR's home
