KBTX has run an anniversary article for Sophia Moreno. On May 11, it will have been thirty-one years since she was last seen in Bryan, Texas. She was only sixteen and a half when she disappeared, but married already, and her family said her husband was violent. No word as to whether he’s considered a suspect, though, and the article (the first I’ve seen on her case) doesn’t mention her husband at all.
It seems highly unlikely that Sophia ran away. Perhaps she might have wanted to leave her husband, but I think she would have contacted her family. The fact that she wanted to know what her mom wanted for Mother’s Day is a strong indication that she planned to stick around, but something — probably something very bad — kept her from doing so.
