When he arrived at his son’s house at 11:00 a.m. on August 8, Medina explained what had happened:

He just said that his wife picked up a knife on him, and they had a big fight, and he shot her, He came to my house, and all he said was, ‘I need to go to the police. I need to turn myself in.

Another neighbor, Paula Trivno, speculated to CBS Miami:

It has to be mental illness, it can’t be someone with sanity.

CBS Miami spoke to another neighbor, Anne Swary, who commented on how “odd” she thought Medina was:

He could’ve knocked on my door and said I just killed my wife and it wouldn’t have surprised me for him to do that. It’s so, so sad and I’m really sorry for her family because she seemed like a lovely woman.

I hope they have no pity for a coward, I hope that god can forgive you because I can’t, what sick person goes and writes a status about it and says that’s something that they have to do. She never gave up she didn’t even give up on that marriage when she should have a long time ago.

The summary of one of his books details an instance where his wife was attacked by poltergeist while they were on vacation in New York, he says, “The author can relate to the world of victims who have been attacked by evil spirits…”. Others deal with his experiences with UFOs, and go through, “his comparison of humans and aliens.” While he also expresses his worry that humanity is not working on a time machine. He writes,

Why are we not acting on working to create Technology for a time travel machine? Why cant we build this for the world for an evacuation emergency plan?

The Miami New Times reports:

Other books talk about the end times, the destruction of the world, and the corruption of the court system.

Medina’s neighbor Anne Swary told CBS Miami that Medina told her that: “He would tell me that he thought he had been attacked by demons in his apartment.”
