For several minutes, the heartbeat continued with a faint sound, which did not bother me as it could not be heard through the wall. Eventually, it stopped. The old man was dead. After removing the bed, I inspected the body. What was the reason for killing this victim?
Explanation
The old man was killed because of his 'cloudy eye,' which disturbed the narrator and motivated the murder. The other options are unrelated to the cause of the killing.
