This happened in Campina Grande, Paraíba state, Brazil.
The victim was 32-year-old J.A.d.S. and she was murdered by her husband, P.N.G.D.
Supposedly, P. was suspicious of J. cheating on him, and repeatedly confronted her about it. One day, when she yet again denied cheating, he got a machete and repeatedly struck her with it.
Immediately feeling remorseful, he got J.'s 13-year-old daughter to get a neighbour to call the police. P. then changed clothes and went to work, where he was arrested.
J. and P. had no children, but J. had three children from a previous marriage and had agreed to take care of P.'s three nephews.
