If it had not been for her friend, the one who found her phone and turned it in to police on July 20, Danni's disappearance might have gone unnoticed as just another single woman with a new car who chose a new life.
Her apartment was cleared out and her things were tossed on the curb by police, her rent was unpaid on August 1 - only fourteen days after her disappearance , there was lots of cash in her apartment that was not used to pay the rent. No one would be the wiser if she simply vanished.
Although work reported her missing, they had no reason to follow up after notifying next of kin. Without DW, this would look like a woman who voluntarily vanished after voluntarily disabling GPS in her car.
