Texas set Wednesday as Ramiro Hernandez's final day. The Mexican citizen was convicted of murdering a man and raping the man's wife multiple times at knife-point.

Hernandez is to receive a lethal injection Wednesday evening at 6 p.m. CDT in Huntsville. This planned execution will be the sixth usage of the death penalty in Texas this year and the 16th in the U.S.

The Mexican government is trying to appeal Hernandez's execution. It says the U.S. has not met obligations for treatment of foreigners taken into custody.

The Mexican Foreign Affairs Affairs Ministry has tried every method possible to stop the execution, but it's run out of ideas.

Hernandez was working for his employer Glen Lich in the south central Texas county of Bandera. He was convicted of killing Lich with a metal bar in October 1997.

After killing Lich, Hernandez is said to have randsacked his employer's home and raping his wife, multiple times according to the Texas Attorney General's office.

Briefly, Hernandez's execution was put on hold while more information on the lethal injection drug was researched. But, that hold was reversed this week in U.S. appeals court. 

This is not the first time that a planned execution has been disputed by the Mexican government.
