Anxiety Attack
Mr. Carl had been stricken with an anxiety attack! It was obvious that the attack was caused by the fear that he developed after the disappearance of his wife. He had worn off after going from pillar to post in search of his wife and so was excessively exhausted. As a result, he stopped breathing and collapsed. The ambulance was called in immediately and Mr. Carl was taken to the hospital. It was to see how much the health of old Mr. Carl had deteriorated.
