A bizarre murder conspiracy case is unfolding in Cranbrook.

Police say the case involves the murder of an innocent couple and has connections to the Hells Angels.

Investigators believe there was a plot to kill 39-year-old Doug Mahon.

Mahon is known to police and had lived at a home where two people were murdered in May.

Mahon had moved out of the house six months before Leanne McFarlane and Jeffrey Taylor were shot to death. Police believe the two were not the intended targets of the shooting.

One of the four men charged in the conspiracy is Chad Munroe. Just over a year ago, Munroe was shot outside the Sam Steele Hotel and survived.

Kevin Winters, 52, faces attempted murder charges in connection to that incident; Donald Faid, 55, also faces weapons and assault charges relating to that incident.

Doug Mahon was arrested shortly after the May shooting and is now facing drug trafficking charges.

Police say they are dealing with a web of gang crime and retribution which has put Cranbrook on edge. "The individuals that are now before the courts, there's a significant link between them and an outlaw motorcycle group that is based in metro Vancouver, " says Shinder Kirk, a member of the RCMP Combined Forces Special Enforcement Unit.

RCMP say their investigation is far from over and they do expect to make more arrests.
