PHOENIX -- The family of a murdered couple is speaking out a week after they were found brutally killed.
The bodies of William Singer, 81, and his 64 year-old wife, Barbara, were discovered last Tuesday in their northwest Phoenix home after a worried caretaker called police.
Police do not have any suspects in the case.
"The only saving grace about all of this is that they will never, ever have to know what it's like to have to live without the other," said son William Singer Jr., who broke down while speaking of the inseparable nature of his parents.
The couple's death was so violent in nature that Phoenix police will not release specific details. Investigators say the motive is unclear as there were no signs of forced entry.
William Singer Jr. recalls the last phone call he made to his dad on Father's Day. "I told him that I loved him and how much he meant to me, and how honored and proud and grateful I was that he was my dad."
William Singer was a Korean War veteran, Air Evac pilot and most importantly, his son says, proud grandpa who taught others to do the right thing. "I believe in the goodness of the people of this community, and I believe that whoever knows something that can be helpful will come forward," said Singer's son.
A reward of $1,000 is being offered for tips leading to an arrest and conviction of whomever killed the couple. Anyone with information is being asked to call Phoenix police and/or Silent Witness at 480-948-6377.
