"I've not had the call like this before, " Krause said as she spoke about the 911 call. Krause was able to calm the boy down, and asked him questions to help police find his location and also gather information about the situation. "I asked him plenty of questions and he was so good, " she said. "He was a little nervous in the beginning, but he did everything I asked him to do. " Krause asked Jackson if his father was awake. Jackson went to check on his father who couldn't give any replies when he called out his name. This led Krause to believe that the man was unconscious (无意识) .
Jackson told his father's name but she was still unable to locate the address. She then asked the boy where he went to school and told him to look at the garage and see if there were any numbers. "I already had a car look for you, " Krause said as she continued to talk to the child.
The boy mentioned a street called Groat Street which is between Huron River Drive and Woodruff Road. With these details, she realized that the boy lived at the southern end of the Brownstown Township. She told Jackson to stand outside his house and wave so that police officers would be able to see him.
Even though Jackson got some of the numbers of his address wrong, police saw him outside his home and the father was quickly taken to a local hospital. He is now in good condition.
The father had been suffering from low sodium because of the medicine he was taking. He told 7 Action News he had taught Jackson and his daughter Mary how to call 911 when something terrible happened to him.
