The elderly couple stabbed by a house guest in their Bellevue home Saturday had apparently taken in their attacker after seeing her struggling and homeless in a park, the second time they had taken in someone off the street.

“Something clearly went horribly wrong,” she said.

When officers arrived, they found Carolyn bleeding in the street and Glenn in the house, both with multiple stab wounds. First responders were also able to put out small fires that had been set throughout the house.
