Mike Warner was just 18 years old when he met Cathy Swartz. Cathy was a single mother with a six-month-old child, Courteney, but Mike fell in love with her. Their love affair bloomed quickly, and within months, they were engaged and had even moved in together.

They had a joyful relationship, and they visualized a beautiful future together. Mike had also wholeheartedly accepted the role of raising Courteney.

On the night of December 1, 1988, before anything went wrong, the couple enjoyed a hearty meal and played board games. They went to bed at midnight, and though four of his friends knocked on their door that night, he asked them to go away. Mike went to work the next morning.

However, when he returned home, he discovered a shocking sight. Cathy Swartz was lying in a pool of blood. Mike immediately called the authorities. An autopsy revealed that Cathy was beaten, strangled, and stabbed in the neck. The killer had also allegedly tried to assault her.

Mike Warner was quick to be suspected, but he was at work the whole time and was cleared off soon after.

Mike Warner went on a downward spiral after the murder. The case was not solved back then, and he turned to alcohol, as revealed by him in a 2023 interview. He revealed that alcoholism became his coping mechanism for a while after the murder.

He did not divulge many details about his personal life, but he revealed that he never married after that. When he heard of Robert Waters getting arrested for the crime decades after the murder and later committing suicide, he said, "Easy way out for him, I guess."
