$30,000 reward offered in 4-year-old Phoenix murder mystery

PHOENIX - A $30,000 reward can be yours if you can help solve a mysterious 4-year-old murder case.

For 45 years of his life, Irving Shuman dedicated himself to his Phoenix real estate business. His family described him as a hard-working father who loved life, and although he was 84, he had the spirit of a man half his age.

When he didn't show up for dinner four years ago, inside the business he started, Irving was discovered murdered.

"This was just an extreme example of brutality," Phoenix police said in a press conference on the investigation in 2008.

Irving's car was stolen and driven to California, but the car was found, his killer never was.

"Unfortunately so far, here we are four years later and we have not solved this crime," Irving’s son, Rick Shuman said.

Irving's children pleaded to the public for help finding their father's murder in 2008, and now again on Friday. Outside of building Irving was killed in, his children Rick and Amy Shuman announced they would give $30,000 to anyone who can bring an end to their father’s cold case investigation.

"I want justice for my dad. Nothing is going to bring him back, but for me I really think I would feel better," Amy said.
