Once Elli had committed the patrol officers and security of the quarantine to her observational skills it was child's play to walk through it without being detected or seen.
Quickly she began her penetration of the area as she sought the point of origin. She touched walls and vehicles as she went deeply into the zone allowing herself brief glimpses into the past so that she might better chose her course and avoid any deep patrols.
Her agile mind began managing the data she was collecting into a living mosaic that continued to expand in volume an depth. Elli had been called in her youth one of the most intelligent members of her field when in fact she was likely one of the top ten intellects in the world. Her IQ was beyond measuring and her memory the envy of any computer.
She didn't think of such things often as it was an unneeded distraction but so far the data she had gathered was as expected in such a disaster area.
She came upon a deceased police officer and touched his corpse drifting back in time as she followed him through his day till point of death.
Satisfied at last she'd found a small part of the puzzle she took the officer's radio and continued her entry and data gathering.
She began scanning the radio channels searching for any current data and soon found an encoded signal that to others would sound like random noise but to Elli soon began to become as intelligible as her native tongue.
