Medina's Facebook posts

Medina posted a picture of a body and an apparent confession to his Facebook page (pictured below) about noon Thursday. Neighbors identified pictures of him as the man who lived in the townhouse.


The photo showed a woman wearing black leotards with her knees bent backwards. Blood covered her left cheek and arm. Medina tagged the photo as Alfonso and captioned it "RIP."

"What sick person goes and writes a status about it and says it's something they have to do?" said Daysi Fernandez, Alfonso's best friend. "He killed her and he posted it."

Miami-Dade police say Medina made both posts, which had hundreds of shares by Thursday afternoon. His Facebook page was removed about five hours after the shooting.

Several community organization pages named Derek Medina appeared on Facebook on Friday afternoon, including one with more than 1,000 likes. Some posted his mug shot while others mentioned his self-published self-help books. The pages asked that friends share them to spread spousal abuse awareness.

Friends: Couple had troubled relationship

Alfonso's friends said the couple had a troubled relationship, but stopped short of saying it was violent. Records show Medina and Alfonso married, divorced, then remarried about three months ago.

Neighbors said officers brought a girl covered in a blanket out of the townhouse. Friends said she was Alfonso's daughter from a previous marriage.

"When they came here, they rushed inside the house and we didn't know nothing was going on and then they carried a little girl out to the car and they were asking her questions," said Oliver Thomas.

Local 10 was told Alfonso's daughter is staying with her father.

Neighbors added that the man acted like the neighborhood watch captain in the community and carried a concealed weapon. They painted a picture of a paranoid man who kept his windows covered and had surveillance cameras pointed at his front door.

"The guy was kind of sketchy, you know, walking around with a gun," said Yoshi Dade. "It's kind of scary. You never know."

"The windows are not even open. There are cameras all over the place," added Paula Traviño. "He's just into himself. His wife just came in and out. That's all I saw."

Medina's paranoia went beyond his home. The 31-year-old wrote a series of e-books with long titles that dealt with relationships and his experience with aliens.
