Mexico City police are offering a reward of $108,000 for information leading to the woman last seen with a school girl found murdered. 

Seven-year-old Fátima Aldrighett was last seen on February 11th waiting to be picked up from school. 

Her body was found 4 days later in a plastic bag.

On the day of Fátima's disappearance, surveillance video from outside her school shows her walking away with a woman. 

Police say they found the woman's apartment following a tip from her landlord but the woman had already fled. Inside the apartment, authorities found Fátima's shoes and her sweater. 

Fátima's murder comes one week after the murder of another young woman, highlighting Mexico's high rate of femicides. 

25-year-old Ingrid Escamilla was dismembered by her partner. According to the BBC, her partner told police he stabbed Escamilla and tried to dispose of her body. 

In Mexico, about 10 femicides, the killing of a woman or a girl because of their gender, happen every day.
