Watch “Nancy Grace Mysteries: Mary Winkler,” Friday at 8 & 11 p.m. ET on HLN.
Mary Winkler seemed to have it all: A picture-perfect marriage, 3 beautiful young daughters, and a husband who served as a beloved minister at a local church. But early one morning, 31-year-old Matthew Winkler was found dead with a gunshot wound to the back in his own bed. After fleeing with her kids, then confessing to shooting her own husband, what happened to Mary Winkler? And what really happened the night Matthew Winkler was murdered? Did the minister’s wife really kill because of years of abuse?
