sounds like a cover story to me, to ambush and kill a US diplomatic worker and her husband in front of their child, over “visas”
It’s not like someone else in the consulate isn’t just going to keep issuing visas
I suspect this lady was involved in more than issuing visas-either officially, or unofficially
A cover story?
This man, Jesus Ernesto Chavez (aka El Camello), could have killed the wrong person. More likely, like you’ve sai, he just likes to kill. It gives him a feeling of power, a thrill.
