Body parts of two children who went missing for almost 3 weeks have been found in chicken boxes after  a man dropped the boxes in front police officers.

Reports indicate that the polices saw nervous man dropping two plastic boxes in Mexico City and proceeded to help him , this is when they found “very white meat” inside the bags.

However, when the officers went over to help, three black plastic bags emerged from the boxes, which have been described as “the kind that polleros use to put chickens in.”

One police officer said: “The person wanted to put the bags back in very quickly, but they were heavy, it cost him work.”

A bag ripped and what the agents found was shocking.

After seeing the “white meat,” an officer realised the bag contained an “arm, shoulder and an ear.”

Edgar then claimed he was unaware of the contents of the bag, however had been paid “two grams of coca” to dispose of them.

The discovery comes after reports of two missing boys, Alan Yahir “S”, 12-years-old and Héctor Efraín “T”,14-years-old who disappeared on October 27.
