Marta Isabelle dos Santos, affectionately known as Martinha, was a 16-year-old girl who dreamed of completing her studies and was known for her singing in church. She had been living with her father and stepmother in Porto Velho, Rondônia, while the rest of her family resided in Paraíba. Tragically, she was found dead in a house on the night of October 24 with visible signs of torture and maltreatment. This shocking discovery has raised significant concerns over child welfare and domestic abuse in the region.

Her father, Callebe José da Silva, confessed to having subjected his daughter to severe abuse, revealing that he would tie her up every night with electrical wires. This admission has prompted outrage and grief among family members, especially as they reflect on the lack of interaction they had with Marta in recent years. Her aunt revealed that their last photograph together was taken during her son's birthday in August 2020, indicating a significant disconnect in familial bonds, compounded by the circumstances surrounding her death.

The case has garnered attention not only for the horrific nature of the crime but also for the broader implications it has on understanding child abuse within families. A video circulating on social media shows Marta singing during a church service, which marks one of the last memories her family has of her alive. This incident highlights the critical need for awareness and intervention in cases of domestic abuse, particularly regarding the welfare of vulnerable children in Brazil.
