9Wants to Know obtained a criminal affidavit accusing Bill and Karen Young of spending the grandmother's money at places such as Macy's, Pottery Barn for Kids, Costco, Netflix, Amazon.com and Comcast.
All together, investigators believe the Youngs pilfered $214,565 from the grandmother's account for their own personal benefit and gain. The Youngs are also accused of using the grandmother's money to take a trip to Las Vegas three years ago.
According to the criminal affidavit, Bill Young had power-of-attorney over his grandmother's assets, but family members became suspicious when the Young's mentioned they would have to start cutting-back on the grandmother's living expenses. An attorney contacted investigators who executed a search warrant at the couple's home last year.
The Youngs are also accused of using the grandmother's money to fund business expenses. The affidavit says checks written out from the grandmother's account to the couple's business account have been found.
"I can't wait for this case to get started so the rest of the evidence can come out. Both Bill and Karen will be exonerated," attorney Susanne Rogers told 9Wants to Know.
Rogers represents Karen Young and said all of the expenses were legitimate. Rogers says she couldn't get into detail about the expenses, but says Karen Rogers is considered a caretaker for the grandmother.
Young runs a website called www.billyounginspires.com where he sells books he has written, promotes his speaking engagements and drums up contract work as a consultant who is hired to help nonprofit companies learn how to raise more money and grow their business model.
He has worked with some of Denver's most well known charities including the Denver Active 20-30 Children's Foundation, Tennyson Center for Children, Denver Post Charities and the 9Health Fair.
Young is also listed as a member of the management team of Talus International, LLC, a local company that according to its website trades health care in an open exchange.
9NEWS contact the business Wednesday for a comment and did not get a response.
According to a bio on the company's website, Young is the author of two books WEBPLICTY and Webplicity 2.0, he served as the president of Denver Active 20-30 Children's foundation in 2006 (an organization that raises money for various children's charities in the metro area). The bio also says Young sits on the board of directors for St. Anthony's Hospital Foundation and Denver Kids Inc. He used to serve on the board for The Tennyson Center for Children but resigned in 2010.
According to his website, Young has upcoming appearances under his Bill Young Inspires business in Dallas, Tulsa and Salt Lake City before the end of the summer.
According to the Westminster Police Department, Young is not allowed to leave the state under the terms of his bond.
"We have learned that an employee of a former contractor of 9Health Fair is under criminal investigation. We are cooperating with the police and have no further comment at this time," said Marla Rodriguez, a spokesperson for the 9Health Fair.
