Medina said he disarmed Alfonso, put the knife in the drawer, then shot her several times after she began punching and kicking him, the report said.
The photo Medina posted on Facebook shows Alfonso, wearing all black and pink socks, on her knees, twisted backward in a bloody heap.
Alfonso’s former boss at a West Miami-Dade Denny’s told the Miami Herald that the husband was extremely jealous and had hit Alfonso in the past.
“She would be bruised up,” said Amada Cooper, who described Medina as a controlling husband who tried to force her to quit her job as a server because he didn’t want her working nights.
After several violent episodes, another co-worker implored Alfonso to leave him. “He would always come back, begging her … come back,” said Cathy LeBella. “She would say he was going to change. She was in love with him.”
Medina and Alfonso initially married in early 2010 after dating only a few months. The marriage was stormy and friends said he would often kick her out. The two always got back together, however.
They divorced in early 2012, then remarried a few months later, records show. Cooper said the two fought often because Medina, most recently a property manager at a posh Coral Gables condo building, could not hold a job for more than a few months.
“He wouldn’t even let her talk on the phone,” Cooper said. “He always waited for her outside. One time, he went storming in, looking for her, telling her to get outside.”
Another friend, who did not want his name used, said Medina once threatened to kill him and another pal on Facebook after deciding “they weren’t real friends.”
He also recalled that Medina, during one of his break-ups with Alfonso, had angrily blasted the young woman on his Facebook page.
At Denny’s, where she worked as a server, Alfonso was known as a dependable worker with a loyal customer base, who worked the graveyard shift to care for her daughter.
“She was a beautiful person,” LaBella said. “Her daughter was her pride and joy.”
She had a quirky personality and loved anything that had to do with ghosts, aliens and the supernatural. She would often utter her catchphrase “Sasquatch” after long nights on the graveyard shift.
“She would just blurt it out. That was her release. She used that phrase a lot,” remembered a co-worker, Tina, who asked that her last name not be used.
As for Medina, who also shared a love of ghosts, his eccentricities were proudly on display online.
He had appeared as an extra on the Miami television crime drama Burn Notice, which he touted on his Facebook page.
Medina was an avid poster of YouTube videos, chronicling his leisure time: pick-up basketball, driving golf balls, sitting in the cheap seats at Miami Heat games, boating, playing the Call of Duty video game. His account had 143 videos.
He was also a prolific author of self-published e-books with long-winded titles: How a Judgmental and Selfish Attitude is Destroying the World We Live Because the World is Vanishing Our Eyes.
A blurb on the back cover of that book notes: “the author has formed his own ghost hunting team and has worked several cases.”
Another book, which centers on ghost hunting, says the author’s wife was attacked by a ghost during a New York trip.
