Public records show that Medina and Alfonso first married in January 2010, divorced in February 2012 and then remarried three months later. Medina bought the condominium unit where the couple lived in March 2012 for $107,000.
On his Facebook page, Medina claimed to be a supervisor at a property management company and to have appeared in the Miami-based crime drama "Burn Notice," though his name doesn't appear in online credits for the show.
On a personal blog to which the Miami Herald linked, someone named Derek Medina touted e-books of his on subjects ranging from saving marriage through communication to "humans who are gifted and can see the supernatural spirit ghost world we live in."
"The author was with his wife in New York and his wife was attacked by a ghost," he writes, describing the e-book. "She was seeing a ghost and was being taunted and messed with. She informed her husband and he told her to go to sleep and he would watch over her. Minutes later he was attacked by a demon ghost and he was sick and throwing up."
Photos posted by Medina on Wednesday show the family enjoying a meal alongside an unnamed marina and lounging beside a swimming pool.
Police said in the arrest affidavit that Medina never called 911, only turning himself in to police after going to see family and confessing.
Thursday night, police had taped off the area around the condo complex where the couple lived. The complex is made up of peach-colored townhouses with faded wood roofs.
Several cars filled the parking area in front of the townhouses as police questioned neighbors and possibly friends of the victim. Some of those gathered were crying.
Neighbor Phil Eby said he didn't know the couple very well but expressed surprise at the shooting.
"I met him a couple of times. He seemed like a pretty nice guy," Eby said. "But I don't remember her at all."
It wasn't immediately clear if Medina had an attorney.
A company official for The Gables Club, a gated, upscale condominium complex in Coral Gables, said Friday that Medina worked there "briefly," but declined to elaborate on when or why he left the job.
A maintenance worker, who would not give his name, said he had seen Medina working at the front desk, taking care of calls and the tenants. He said was "a very nice guy, polite."
When he saw the news this morning and Medina's picture, the worker said, "It can't be. He's too nice."
