It does sound like she may be just renting a room which may change her rights from a whole house rental but it still doesn't mean she automatically gives up all rights entirely to determine who comes and goes.
The homeowners welcomed her into their part of the house. A living room or foyer im assuming. Then casey retreated to the basement (her part of the house). The OP didnt say they chased her into the basement, they tried to have her come up and talk to them. Then they called the police.
This is how i read it, though i could be reading it wrong...
