My older sister lives in the country in between Velma Oklahoma and Duncan Oklahoma near the Fuqua Lake area, this story was told by a rural mail delivery woman who delivers the mail in the country.
The incident happened while she was on her route, when she came upon to the mailbox a male Chinese nation came out brandishing a, AK-47 rifle being very hostile,
I don't know if he pointed it at her since it is against the law to do so but she was terrified and said she was never going back and that the location that had a guard tower. Was the sheriff department notified, I don't know, did she notify her supervisor, don't know. But word is from the country folk who live in the area they have seen the guard tower at the pot place;
I refuse to call it a farm because it is an insult to farmers.
And yes she was traumatized by that ordeal
