The Case of the Victim's Clue

When John Fischer found Hans Krupp, the old man was lying down in an alley. He felt that something was wrong, so he call 911. An ambulance soon arrived and Krupp was taken away to a hospital. Detectives Davis and Moreno were also in the area and asked Fischer some questions about the incident.
“I was on my way to the store when suddenly I heard this moaning sound,” Fischer explained. “I looked into the alley here and there I found this old guy on the ground. At first, I didn’t know if he was having a heart attack or what. Then I saw that he had this big gash on his forehead. I got suspicious, so then I got help.”
“Did he say anything to you?” Moreno asked.
“He didn’t say much. Mostly all he did was moan,” Fischer replied. “But he did say one word, “hune,” yes, that’s what it was. He said “hune,” and then he stopped speaking completely.”
“Did you see anyone else around?” Davis asked.
“No,” Fischer said.
Later, Moreno called the hospital in order to get more information on Krupp’s condition. He reported his findings to his partner.
“Krupp’s in a coma now. His doctor isn’t certain that he’ll be able to recover. I did learn one thing, though. His wife told me that he was an immigrant for Germany. She said that sometimes when he got excited or talked in his sleep, he would speak in German. Maybe he left us some kind of clue as to who attacked him,” he said.
“Maybe we can find out more by talking to a few people in the area,” Davis replied.
The first person the detectives questioned was Nick Hightower. At 6 feet, 10 inches tall, he looked very intimidating.
“You say someone got mugged?” He asked. “No, I don’t know anything about it. I’ve been playing basketball all day.”
Randy Walmar was one of the biggest men they had ever seen. He must have weighed 400 pounds.
“Someone got beat up? Where’s the neighborhood going these days? I just got back from the store. This is first I’ve heard of it,” he said.
Charles Zelman regularly rummaged through people’s trash in the alleys.
“I haven’t seen anything. I tend to stay out of everyone’s way. I’m not looking for any trouble, you know,” he said.
Zack Richards seemed really interested in the case when the detectives talked to him.
“Who got mugged? Old man Krupp, you say? Yeah, I know him. Is he all right? No, I just wanted to know,” he replied as he took off on his skateboard.
“Do you have any clues?” Moreno asked.
“I’ve got a pretty good idea,” Davis said.

WHO DID DAVIS SUSPECT?

THE ANSWER
He suspected Nick Hightower. Krupp’s clue was the word, “hune,” which means “giant” in German. Fortunately, Krupp recovered and identified the basketball player in the attack on him.
