Calling it an unwinnable case, Jefferson County District Attorney Bob Wortham said Monday he's dropping criminal charges against a retired security guard accused in the July 2016 death of a woman who was shot outside a Port Arthur convenience store. "The law is against us," Wortham said. "It's a case we don't think we can make." Michael Turner, 68, was indicted in August 2016 on a charge of criminally negligent homicide, a state jail felony carrying a maximum of two years in prison and a $10,000 fine.
