A Clinton Township family has now upped the reward for any information leading to arrest of the person who killed a husband and wife 10 months ago.
Louis Rahhal told a crowd gathered outside the Clinton Township Police Department, "The more you love someone, the more you grieve."
The family is now offering a 50-thousand dollar reward, after Jim and Christy McKeogh were found beaten to death inside their Clinton Township home in January.
Christy's other brother Michael Rahhal tells us, "I strongly believe we may be dealing with a serial killer."
So far leads have dried up. Police say there were no signs of forced entry or a struggle.
Michael Rahhal had this message for the killer, "I say to him, you killed two people, but you killed nine of us. You need some help and I hope you turn yourself in."
If you have any information on this double murder, call Clinton Township Police or Crimestoppers, and remain anonymous.
