City Morgue.

The Coroner conducted a full autopsy
for the mature woman and the young girl.

They have been poisoned by a toxin:

Carbon Monoxide (CO)

Common fumes caused from burning fuel
in cars, trucks, stoves, furnaces, even fireplace.
Most lethal indoors, in closed spaces.

Like a Mini Cooper with the windows rolled up.

The mature woman had 50% of ‘CO’ in her body.
And the young girl had 41% of ‘CO’ in her body.

Time of death estimated to be between the hours of
12:45 PM – 2:45 PM on the same day they have been found.

Confirmed, both victims suffered from the same ‘CO’ source.

Now, came the question: 

          Was this an Accident? Or was this Murder?

No witness.
No weapons.

Where should the police start looking?
