The Peña murder looks like it was due to affairs of the heart and wasn't another ho-hum, run-of-the-mill Mexican narco terror murder.
Valley Morning Star : Local News: Deputies probe singer’s death | peña, tamaulipas, mexican: "Tamaulipas State Police believe that Gonzalez’s ex-boyfriend killed her and Peña in a rage over a lesbian affair."
And the Houston Chronicle points out that that other dead Mexican singer was also killed in a way that indicated love's mysterious ways might have been involved:
Hijacked by armed men after leaving the stadium early Sunday in Morelia, the capital of violence-plagued Michoacan state, Gomez was tortured — his genitals burned and his body badly beaten — and then strangled, investigators said. His body was found Monday.
Could it have been a gay killing in this case as well? Would that be just too symmetrical?
