Her brother even escorted her to the bus station that morning to make sure she was OK on her way to work.
"When she got on the bus, my brother told her, 'If anything happens, just call me.' Ten minutes later, his phone rang and it was her. All he could hear was her screaming, pleading for help," Moreira's sister, Andreza da Silva, says.
The bus had just been pulling away when the father of Moreira's four children, Marcos Antonio da Silva, jumped aboard.
"He went straight to where she was. He wanted her to get off but she refused. They started fighting and she said she wouldn't go with him. That's when he pulled out his knife. He stabbed her 21 times," Silva says."
