NEW HOPE, Pa. (CBS) – Five members of a Bucks County family are facing charges for allegedly conspiring to defraud insurance companies of more than $20 million to live an “excessively extravagant lifestyle” that included exotic sports cars, “Romanesque murals” and more.

According to Attorney General Kathleen Kane, an investigation began after an October 2013 fire at Claire Risoldi’s home in New Hope, which she referred to as “Clairemont.”

Officials say this was the third fire at the home in the past five years, including one in June 2009 and another in August 2010.

Following each of the fires, the Risoldi family – which also included Claire’s husband, Thomas French; her son, Carl; and daughter-in-law, Sheila – filed insurance claims. Those claims have paid out more than $20 million in claims for the fires.

The Risoldis are reportedly seeking $20 million more in claims filed for the Oct. 2013 fire, including $10 million for jewelry that a Grand Jury found Claire Risoldi falsely accused the volunteer firefighters who put out the blaze of stealing.

The Grand Jury also established the Risoldi family had a 20- to 30-year history of filing “questionable” insurance claims, such as in one case, when it was found that Claire Risoldi still had jewelry she claimed was stolen back in 1993.

Investigators say the family progressively increased the value of the jewelry covered by their insurance policy from $100,000 to almost $11 million, with the final increase occurring 25 days before the 2013 fire. Additionally, in all three fires, the Grand Jury found there were large amounts of flammable materials in piles near the points of origin.

Claire, Carl and Carla Risoldi are also said to have facilitated the receipt of invoices inflated more than ten-fold for “Romanesque murals” inside Clairemont depicting the family “in flowing robes gazing down from the heavens.”

Among other things, Claire Risoldi is also accused of witness intimidation, including threatening an insurance adjustor and an attorney involved in one of the real estate transactions.

The investigation also resulted in the seizure of $7 million in assets, including about $3 million in seized bank accounts, $1.2 million in jewelry, six Ferraris, two Rolls Royces, one Cobra and four other vehicles worth $2.8 million.
