Mystery Surrounds Death of Young Trans Activist in Calif.

Police have not yet concluded what killed Zoraida "Ale" Reyes, a transgender woman active in Orange County LGBT and immigrant causes.

An inconclusive autopsy did not reveal how Reyes died and ended up behind a Dairy Queen in Anaheim, but Orange County officials are performing a toxicology report to find out more.
