A 46-year-old man has been charged in connection with the alleged murder of a teenager in a suburban Christchurch park this weekend.
And while they are still seeking the person who pulled the trigger, police believe they know who the culprit is.
Connor Whitehead, 16, died in Casebrook on Friday night after what police have described as a firearms incident.
An adult male was assisting police with the investigation, dubbed Operation Stack.
