Who Done it?

The tiny little village of Nothinghappenshere was shocked at the early morning news. A murder had been committed. The body had been discovered by a jogger in the woods near town. The body was taken to the town doctor to be examined so that cause of death could be determined. The town constable had questioned the jogger, who found the body, hoping to gather clues as to what happened. The only real information the jogger could provide was that the victims digital watch had been struck during the assault and had stopped at that time. The jogger had scribbled the time displayed on a piece of paper which he handed to the constable. (below is a copy of the note):


After a frustrating morning, the constable contacted Solvz-it-All detective agency in a nearby town to help solve the crime. Two investigators, Cam and Chris, arrived to help. After questioning everyone in town, and determining that no outsiders had visited the village for at least 2 weeks, they came up with 4 suspects. The suspects, Karl, Knightmare, Wiz, and Ragknot, were summoned to the town hall where Cam and Chris questioned them. Here is the information and comments they gathered:



The suspect who admitted being in the woods at 3PM said, "Either Karl or Knightmare is a lawyer, and the other one is a grocer. I'm sorry ... my memory is just not what it used to be".



The suspect who arrived at the town hall at 5PM, to give his statement, said, "Karl has an occupation ... I believe it begins with "G", and neither Wiz nor I is a pharmacist".



At 8PM, another suspect arrived to provide information. "Either Knightmare or Wiz lives on my street", he volunteered.



The last suspect, who arrived at 9PM, said, "I am neither a pharmacist nor a geologist".



Detective Cam said this seems straightforward. His partner Chris cautioned, "Watch carefully, and lets reconsider all the comments and evidence ... something is not right!"



Help Cam and Chris find the person and occupation for each time, and most important ... WHO DONE IT?
