根据短文内容，完成下面表格。

　　Many people believe in the existence of an animal that is half human and half ape(猿)．

　　In 1958 a young man named Jerry Crew was on his way to work．Mr．Crew worked for the Wallace Construction(建筑)Company in California．He drove large construction equipment for the company．It had rained for the past several days and the area was very wet and muddy(泥泞的)．

　　As Jerry Crew walked toward the vehicle he would drive that day, he saw something extremely unusual．What he saw frightened him．There, in the mud, were footprints－footprints that were almost ten times larger than a normal human foot．

　　Newspaper reporters found out about the huge footprints．They talked to Mr．Crew and took pictures of the footprints．They published stories all over California．One newspaper story called the creature that made the prints “Bigfoot”．

　　In 1967 a man named Roger Patterson used a small movie camera to take pictures of an ape-like creature moving from a clear area into a forest．Many people said this proved Bigfoot was real．

　　In 2002 a man named Ray Wallace died of heart failure．He was the man who owned the Wallace Construction Company．Soon after his death, his family told reporters that Mr．Wallace had invented Bigfoot as a joke．They told how he had made huge feet out of wood and tied them to his shoes．They said Ray Wallace left the footprints that Jerry Crew found．

　　The Wallace family said the joke became bigger and bigger and Ray Wallace just could not stop．He was having too much fun．For example, in 1967 he dressed his wife in a monkey suit with large feet．Ray Wallace and Roger Patterson filmed her walking into the woods．

　　Many people say the Wallace family were lying．These people plan to continue their search for Bigfoot．Several organizations are still searching for the creature．Chinese scientists are gathering evidence and reason to believe there is Bigfoot living in the mountains of Hubei Province．
