This is the care giver of the old man. Right now he is a mental hospital because he went insane.
The care giver was insistent on having the old mans eye out of sight. He took matters into his ow hands and proceeded.
Every night for about 7 days he would stare into the old mas's soul. He couldn't handle the old mans eye anymore. On the eight night, he stuck his head in the door and took him an hour to get inside because he was scared that the old man would awaken.
I killed the old man :(
The caregiver had suffocated the old man with the mattress until he died.
The caregiver needed to hide the evidence of the crime, so that when the cops come in, they don't see any little evidence of any crime. Therefore he hid every body part in the bathtub.
As time had passed, eventually the caregiver had admitted that he sadly murdered the old man.
