Victim Godinho married Valdeli Mafra in October and became pregnant months later.

 Grimm broke news of her own pregnancy via her Facebook page November 17, 2019, and in January shared a second post in which picked out the name of her child although she didn't reveal the gender.

Authorities said that Grimm suffered a miscarriage some time in January but kept it a secret from her family members. Over the following months she browsed the internet for pregnant women and lied that she was still expecting a child.

Grimm eventually formed a relationship with Godinho on social media and planned a baby shower. Grimm then contacted the guests and called off the August 27 without Godinho's knowledge.

Surveillance video footage aired by G1 showed Godinho entering Grimm's car before the pair drove off towards the abandoned pottery yard where the expecting mother was killed.

Her family filed a missing person's report later in the evening after she failed to come home and her body was located by her husband and mother approximately at 9am on August 28. 

The lead detective in the murder case, Paulo Alexandre Freyesleben dee Silva, confirmed Godinho's death was caused by a sharp cut to the abdomen and wounds from a brick. 

An autopsy will confirm if the baby was removed with the pregnant woman alive or if she was already dead.

Godinho, who studied pedagogy and worked as a substitute teacher, was buried in the Municipal Cemetery of Canelinha after a brief ceremony.
