The Grand Rapids Press has the story on how Edwin Lario(s) Munoz strangled Silvia Sanches-Parada and then attempted to kill her husband, Leoncio Garcia-Lopez, with a knife.
Earlier in his life, Munoz testified before Congress and was featured on the cover of Parade magazine in 2002 after he alleged that he was abused in a jail after getting caught crossing the border.
Here are some background stories and his testimony.
The Grand Rapids story also discusses how the unborn child, named Luz Maria, was baptized and will be buried in her mother's casket.
It is possible that Munoz will be charged with two murders (mother and unborn daughter) along with attempted murder.
