A second victim of Saturday's shooting at a South Florida gym died of his injuries, authorities said Sunday.
Marios Hortis, 42, was one of two people shot by 33-year-old Abeku Wilson, who had been let go as a trainer Saturday at the Equinox gym in Coral Gables "due to workplace violence and was escorted off the premises."
Investigators say Wilson returned to the gym with a handgun and fired multiple shots at Hortis and 35-year-old Janine Ackerman, the facility's general manager, before fatally shooting himself. Ackerman was pronounced dead Saturday.
Police did not elaborate on what the "workplace violence" by Wilson involved.
Equinox issued an email statement Sunday that it was "deeply saddened" by the deaths of its two employees.
"Our love, prayers and condolences are with both families during this terrible time. The collective Equinox community will always keep Janine and Marios in our hearts," the statement said.
Marc Sarnoff, who previously trained with Wilson for two years, saw him at the gym before Saturday's shooting and noticed something was wrong.
Wilson typically was "very buttoned up, very proper, very appropriate," Sarnoff said in a phone interview. But on Saturday, Wilson physically bumped into Sarnoff and his current trainer. The usually adept Wilson seemed noticeably off-kilter.
"He wasn't clean-shaven ... and he seemed to be slurring his words," said Sarnoff. "He said, `I'm sorry, I'm just off balance this morning'."
An Instagram account in his name is filled with shirtless, muscly photos talking about body building competitions that he was preparing for. In December, a posting said he had gotten a blue belt in martial arts.
The shooting happened about 1 p.m. Saturday at the upscale Shops at Merrick Park. Shoppers, diners at mall restaurants and people in workout gear ran to safety or took cover after reports of gunfire.
"Five gunshots," Ovi Viera, who was in the men's locker room, told The Miami Herald. "It was too loud for it to have been a weight dropping. Within two seconds, people just started running out."
Wilson trained Eveliny Bastos-Klein shortly before Saturday's shooting. She told The Miami Herald that he didn't seem distracted and that she didn't notice anything unusual during their session.
The mall is a few miles from the University of Miami campus. Ackerman studied on a field hockey scholarship at Florida International University.
University Vice Provost Steve Moll, who taught Ackerman while she was working on a master's degree in hospitality, described her as "the whole package."
"She was smart, she was athletic, she was charming, she was determined," he said in a phone interview.
He said she was a hard worker who shined at everything she set her mind to. The New Jersey native was once chosen out of more than 1,000 students as the student leader for the prestigious South Beach Wine & Food Festival and later went to work at the Fontainebleau hotel, he added.
She'd been promoted to general manager of the upscale gym in August.
"My initial reaction was, `No, this can't be. Why would anybody want to hurt such a lovely person'," he said.
Friends and colleagues described Hortis as a beloved spinning instructor with a generous spirit and warm demeanor. A photo of Hortis clad in black workout clothes, sitting on a bike while leading a class circulated online.
