A Vinalhaven man who cared for pop artist Robert Indiana during the final years of the artist’s life is denying allegations made by Indiana’s estate this week that he neglected his duties as a caretaker. Jamie Thomas, through his attorney, Thomas Hallett, issued a statement Friday in response to legal documents filed Wednesday by attorneys representing Indiana’s estate that claim the artist was living in squalor while he had $13 million his bank account, which Thomas managed. The documents were filed in response to a lawsuit brought by Thomas earlier this summer in which he was seeking $2 million for legal fees.
