Artist adding Marlen Ochoa Lopez's baby to mural in Chicago

An image of the baby who died after being cut from his mother's womb is being added to a mural of his murdered mother.

The artist started drawing Yovanny Jadiel Lopez on Friday in East Pilsen. The mural is expected to be finished Saturday or Sunday.

Yovanny died last week, just a couple months after his mother - Marlen Ochoa Lopez -- was murdered. Three people are facing charges for the crime.
