MARION, Texas -- Investigators have identified a skull and other remains found in a South Texas field as a missing San Antonio woman.

Twenty-four-year-old Sarah Gaitan had been missing since last October.

The Guadalupe County Sheriff's Office notified her family of the positive identification on Friday.

So far, they haven't determined the cause of death.

Back in March, a farmer was fertilizing a field near Marion when he noticed a human skull and other bones.
