Kenneth Kanehl Jr., 39, and his girlfriend Pamela Barnes were found dead from gunshot wounds to the head inside a rented home on Brunswick Boulevard in Waterford Township, Michigan. Police carried out a welfare check on July 6, 2005, after the couple had last been seen together at a July 2 gathering and then went quiet; neither the scene nor signs of forced entry suggested a random break-in or robbery. Investigators described the killings as deliberate and targeted, and family and authorities have said the crime felt personal—an execution carried out with purpose rather than in panic.

Police named a person of interest early in the inquiry but did not have enough evidence at the time to proceed with warrants. Detectives later executed a search warrant in September 2010 in Milford connected to the investigation, yet no arrest has been announced and the killings remain unsolved.

Does anyone who knew Kenneth or Pamela have information that could help investigators?
