HARTFORD, Conn. (AP) — A reputed Connecticut mobster who authorities believe has information about the largest art heist in U.S. history remains hospitalized after being injured in jail, and his trial on weapons charges has been postponed.

A lawyer for Robert Gentile of Manchester said Friday that Gentile remains hospitalized “in bad shape” after he fell last month at the Wyatt Detention Facility in Central Falls, Rhode Island.

Prosecutors believe Gentile knows something about the still-unsolved, 1990 theft of $500 million worth of artwork from Boston’s Isabella Stewart Gardner Museum, because another gangster’s widow claimed her husband gave Gentile two of the paintings.

Gentile has denied knowing anything about the theft.
