Seth and Lisa, who both have a passion for law enforcement, get married after dating for seven years. Seth, inspired by Lisa's father, becomes a jailer for the sheriff's department but their love story takes a heartbreaking turn when Lisa dies in an accident while Marty, a deputy and friend, goes to break the news to her husband.
When a pregnant Iowa mom is shot dead in her home, the police scramble to find her killer. With no clear suspect, the investigation stalls until detectives hear rumours of a bitter war between neighbours and begin to investigate.
Seth shares that he had been texting a co-worker named Rachel, but denies that he was having an affair. Meanwhile, investigators finish their forensic work on the scene, and Lisa's family members remain convinced that Seth did not kill her.
In the second trial of Seth Techel, the focus remained on the murder weapon - a shotgun - that only Seth had access to. The prosecution also called a young friend of Seth's who testified to his deceitful and manipulative nature, and emotional testimony was given by Lisa's friend and the cauldwell family.
Defense attorneys in Seth Techel's third murder trial attack investigators' work as inadequate and focus on the inconsistencies and lack of evidence in the prosecution's case.
Seth Andrew Techel was found guilty of murder in the first degree and non-consensual termination of human pregnancy for the death of his pregnant wife, Lisa Techel. In the end, justice was served for Lisa and her family.
