     Jerry Baldwin was 30 years old. He was the manager of a pizza restaurant. He lived in an apartment

about one mile north of the restaurant. He walked to and from work. When it was raining, he took the

bus.

     Jerry loved gangster (匪徒) movies. When a new one came out, he would go to the theater and

watch the new movie three or four times. Then, when it went to video, Jerry would buy the video at

Barney's Video Store. Jerry had a home collection of over 1,000 gangster videos. Old ones, new ones,

color, black and white, English, Spanish, and Japanese-he loved them all. He could tell you the name of

the movie, the director( 导演), the stars, etc.

     Jerry finally decided that he would like to own a gun, just like the gangsters. So he saved his money

for some years. Then he went to a gun store and bought a used gun for $300. While there, he also

bought many bullets (子弹) .

     The following Saturday morning, he went to the gun club to practice with his new gun. He was in the

club for only 10 minutes when he dropped his gun by accident. The gun went off (走火), and the bullet

went into Jerry's right leg.
