Real estate executive Steven Good was found dead on Monday in his Jaguar in a forest preserve outside of Chicago. Good, whose work has taken him all over the country, died of a self-inflicted gunshot wound, according to the Kane County Sheriff’s Department. Good, who was 52 years old, was the CEO of Sheldon Good & Company, a firm founded by his father in 1965. According to his bio on Sheldon Good’s Web site, Good had been involved in the sale of $4 billion in real estate, and before joining the company, he worked for the United States Senate in Washington, D.C. He penned the book “Churches, Jails and Gold Mines…Mega-Deals from a Real Estate Maverick,” published in 2003. In a prepared statement Monday, Sheldon Good President Alan Kravets said it is “a testimony to Steve’s leadership that Sheldon Good & Co. remains well positioned for the future [and] poised for significant growth.” The company has auctioned off properties including 21 of 90 units in a closeout sale at the Ocean Grande development in Rockaway Park in Queens, in 2007.
