Yonatan Molina (21) is accused of murdering Teresa Pepe (72), in Quilmes Oeste. The prosecution is already working on the motive of a robbery aggravated by the use of a knife followed by death.

Molina's aunt, a resident of the area, testified before the media on Tuesday morning. “We do not agree with what he did and we want him to pay for it,” said his aunt. According to the prosecution, police officers in the area already knew that Molina was escalating into violence.
