Help sleuthing an old case

[ssarahbg]

I apologize ahead of time but I am needing some help sleuthing some info on old case that my mom told me about when she was living on Bergstrom Air Force base in Austin Texas. Back in what she thinks was 1974 or 75, there were multiple murders on the base and we were trying to see if the murders were ever solved. She remembers one case in particular of a woman named Sylvia who was stabbed to death multiple times. Her husband came home on his lunch to find her that way. She could not remember much else from the case but that her husband was Hispanic and she may have been as well. If anyone could help finding info, I would greatly appreciate it! Be up for a challenge! I could not find anything through multiple google searches.

These weren't on the base but occurred in the right time frame.

I found a 1979 Austin case of a man finding his wife murdered in bed, but nothing else, including the date, fits your specifications.

This occurred in the time frame you mention but it was in Tarrant County Texas not on Bergstrom AFB.

noodler2, in the case you mention is this the one where the husband came home for lunch or dinner and then went back to work and came home again later and found her dead?

Thank you. I gathered some more info from my mom. It didn’t actually happen on base but it was a wife of someone in the military. The wife’s name was Sylvia and the husband was Juan. The husband came home at lunch to find his wife slain with multiple stab wounds. Also, an 80 year old Bergstrom base librarian was killed within a short time of this happening. She remembers those two murders and maybe a few more during this time. It was approximately 1975 because it was when my oldest sister was around 2 (born in ‘73) and before my middle sister was born (feb ‘76). I am just curious if the murders were ever solved. I don’t think it was related to the case in the article though.

Ok try this one: Jeffery Lee Griffin | Murderpedia, the encyclopedia of murderers
This guy killed a man and a 7 year old boy and later confessed to stabbing a woman named Sylvia Mendoza in 1978. She is mentioned about half way through the article and it doesn't mention any other aspects of her life like if she was married, etc.

Thank you! This seems like the case. Maybe my mom has some of the details wrong. I’ll ask her again.
