Machete found in Akl reserve five months after killing.

"This is not over". That is the message from Auckland police as they encourage anyone who knows anything about the killing of American university student Kyle Whorral to come forward. The 33-year-old was attacked at a bus stop over Easter with a large bladed weapon and died in hospital. Auckland police have revealed they have found a machete but say the hunt for everyone who was involved in the killing goes on. Kim Baker Wilson reports.
