Jurors in Hidalgo County found Nelson Garcia Delgado guilty of capital murder. He has been sentenced to life without the possibility of parole for killing and staging the death of his pregnant, common-law wife on September 29.
Garcia washed her, put her body in his car and wrecked the vehicle in order to cover up the crime.
In a confession, Garcia told investigators the couple had been fighting over an affair Zamora accused him of having. During the argument, Zamora told him she had aborted their baby.
Officials say Claudia Zamora was three months pregnant, at the time of her death.
