Alan Thomas Waters was found dead in his Baton Rouge, Louisiana, home in May 2004. He was 53, a chemical engineer and real estate investor who had moved to Baton Rouge from Wakefield, Massachusetts. Authorities determined he died from a gunshot wound to the chest sustained during an argument between Alan and his ex-wife, Jan Waters, about their two children.

The investigation led to Jan Waters’ arrest and charge in connection with Alan’s death. She was released on bail in March 2006. In October 2010 she pleaded guilty to the lesser charge of manslaughter and admitted to shooting her ex-husband; a state district judge sentenced her to 20 years in prison at that time.

Did anyone who knew Alan or his family in Baton Rouge around 2004 notice tensions that could shed more light on the argument?
