James Huberty was a sullen and crappy person who loved guns and hated people. After many different jobs, he finally moved his family to Mexico in 1984, but that didn’t go well with the family moving three months later to San Ysidro, California.

After losing yet another job in July of that year, James took his family to the San Diego Zoo and to McDonald’s for lunch. That evening he visited another McDonald’s but for a completely different purpose.
