The incident happened in the 1700 block of Ronda Street in Nutbush just before 9 p.m. Thursday night.
When officers and paramedics arrived they found David Perkins unresponsive in the front yard with an apparent stab wound to the chest. He was pronounced dead on the scene.
According to police, the victim's wife Teresa Post confessed to stabbing the man after they got into an argument. She said he told her he wanted a divorce and then walked outside the home. As she watched, she said he bent down and appeared to be cutting the tires on their vehicle.
Already having a kitchen knife in her possession, she reportedly told police she went outside and stabbed him when he turned around to face her.
Police recovered a silver kitchen knife on the scene near the suspect.
Melissa Nelson lives nearby and says she heard the couple had troubles.
She's a domestic violence survivor and thinks there is most likely a lot more to the story than what happened Thursday night.
"Sometimes when women are pushed to a point, and they feel there is no way out, maybe she was in that situation that she had been abused to the point that she needed to — that was her only solution," Nelson said.
