What happened to Herbert and explain why he wasn't in anymore pain?

Herbert was badly hurt when he got caught in the machinery at work. He wasn't in any pain because he was dead.

"Is he hurt?" demanded the mother wildly.

The visitor bowed in assent."Badly hurt," he said quietly, "but he is not in any pain."

"Oh thank God!" said the old woman, clasping her hands. "Thank God for that! Thank - "

She broke off as the sinister meaning of the assurance dawned on her and she saw the awful confirmation of her fears in the others averted face. She caught her breath, and turning to her slower-witted husband, laid her trembling hand on his. There was a long silence.

Herbert was mangled in a machine and died shortly after therefore making it to where he was no longer in pain, the family recieved the 200 pounds as inheritance.
