“Vallum confessed to the killing, which he said was motivated by his fear of how he would be judged by gang members for having a relationship with a transgender woman.”
Vallum is not the brightest person in the town.
He admitted to murder and said it was not self-defense.
Instead, he said that he feared what other people would think.
No self-defense, no insanity plea, Vallum is just a murderer.
Criminals are generally stupid. Wife was on a murder jury where accused would have walked on the murder charge had he said “x pulled a gun on me and I drew at same time and shot first”, but he said the other guy FIRED and the plant gun he put on him had an obstructed barrel (like filled with lead to de mil or be an inert) and couldn’t have possibly done so.
