Geriatric blood storm

I attack an old woman turn 91.
After tying her gagging and hit her strongly i suffocated her with a pillow.
I tie the cadaver with the cord of a curtain.
Days later, another victim.
This time of 89 years.
I suffocated her with a plastic bag.
My crimes became more violent and of an extreme cruelty.
My following victim was retired from 71 years.
After gagging her and tying her with a cable,
I hit her with such a force that i broke their nose and jaw. Then i used a muffler in order to strangle her.
Most of the bones from the right part of the body were destroyed, and I tortured her until death.
She had the mouth and the throat burned by acid.
I forced her to ingest flat caustic.
The lack of love had become me hard until the point of ignoring the suffering with th victim didn't have pity.
I only attack to the weak people
