But she wanted even more, and she knew she could make it happen.

She just had to make sure to keep a steady rotation of tenants.

Dorothea also pretended to be much older than she was.

She wore large framed glasses and colored her hair white so that she'd appear elderly.

This helped her trick people into thinking she was frail and harmless.

Dorothea's mind games didn't end there.

She also started encouraging some of her tenants to go out and enjoy local bars.

She chose people who she knew had struggled with alcohol addiction in the past, and she even gave them cash.

Then, after a couple hours when Dorothea figured they were nice and liquored up, she'd call the police and report a drunk in public, which they'd be arrested for.

They'd usually end up behind bars for 30 days, which was enough time for Dorothea to move someone else into their room and kill them before the original tenant came back.

That is just utterly cold-hearted.

Do you think she views life as a game of survival of the fittest, and so she doesn't feel any kind of sympathy toward others?

Dorothea's tactics only got more diabolical from there.

She used former residents' IDs, including Ruth Monroe's, to fill prescriptions for sleeping pills, which she used to drug and kill her victims.

Then she rolled their dead bodies up in plastic tarps that she'd placed underneath their bedsheets.

Usually before killing someone, she isolated them from everyone else first.

She'd keep people restrained in their bedrooms and tell the others they'd fallen ill.

That way, Dorothea thought no one would be surprised when the person passed away.

If other tenants or even the neighbors ever asked about someone who'd gone missing, Dorothea would make up excuses.

Sometimes she said they'd moved to another city or that she had to move them into a hospital.
