My alcoholic mother took my elderly grandfather over to Mexico without any medications or his passport

Location: Texas, United States

My family is seeking help regarding what we can do. We believe he is in danger. We initially called police to try to stop her from taking him, but they said they assessed his ability to make his own decisions to go with her and they couldn’t stop him because he is an adult. He is 91, has dementia, is a diabetic, and has other health issues that require medications. Because he doesn’t have his passport, we are worried that even if he wanted to get back into the country, he wouldn’t be able to with the state of our borders at this time, even though he is a legal citizen.

A little background. She is a narcissist and our entire family has gone no contact with her due to her abuse and toxic behaviors. It was discovered earlier this year that she had been taking advantage of my grandfather claiming she needed money to pay bills for him, but she had actually stolen approximately $34,000 over the span of the last year and a half or so. We have since transferred the power of attorney over him to my aunt, who he lives with. There is an ongoing investigation from Adult Protective Services against her for her financial abuse of him.

She was able to convince him to go because she knows he loves going to visit Mexico. He was born and raised there, and has a house over there that some family members help take care of while he lives full time in the U.S.. He doesn’t get to visit often, but loves when he can go. Though we have tried explaining to him what she has done to home and that she isn’t in a good state of mind and could be dangerous, he doesn’t understand and can’t remember from day to day. He just trusts her as his daughter.

We just learned also from some family that spoke with my mom over there and are keeping us updated that her plan is to come back to the U.S. in a couple of days and leave him stranded over there without any way of getting home.

If anyone has an advice on what actions to take, we would appreciate it! We are worried at this point that he could be in serious danger.
