Usually, they squabbled about money. Often, one friend told investigators, Calderin would find him watching pornography. She also discovered that he was picking up women through the Internet.
“He was very aggressive. He would hit her. They were always fighting,” her friend Lourdes Guerra told detectives. “He would very frequently give her bruises, black eyes.”
About seven years ago, Guerra told police, she saw Maqueira grab her by the hair and throw her to the ground.
“She told me one time that he said if he ever saw her with another man, he was going to kill her,’’ Guerra said.
Though her husband was never arrested, Calderin complained to the courts. Twice, in 1996 and again in 2009, Calderin alleged domestic violence and sought a restraining order against him, records show.
Still, she continually accepted him back. Calderin often left for days at a time, sometimes staying at shelters for battered women. Finally in July 2012, after meeting another man at a South Miami-Dade supermarket, Calderin left the home and filed for divorce and a restraining order.
For his part, Maqueira later told police, he had no idea why Calderin left “because she was treated like a princess,” adding “she was lazy and only cared about shopping.” Her friends told police he “brainwashed” his two youngest children, portraying her as a drunk.
Miami-Dade police say her departure roiled Maqueira. He began stalking her aggressively. One of Calderin’s friends said Maqueira sent angry texts, such as “die whore.” Employees at Floyd Elementary told police they frequently saw Maqueira parked across the street in his black Mercedes Benz, watching her.
The conflict escalated in August 2012, when Maqueira found Calderin and new boyfriend Dagoberto Vasquez at a West Kendall Laundromat. Maqueira, with his two younger children in tow, harangued her for more than 20 minutes before Vasquez called police, he said. Maqueira left.
The same day, Calderin and Vasquez — who she had moved in with — drove to Islamorada to fish off a bridge. Vasquez, trying to hide a small container of fish he believed had exceeded the legal limit, kneeled down to hide the catch under the chassis of Calderin’s SUV. That’s when he noticed a GPS tracking device, planted by Maqueira underneath the car.
“It’s so easy,” Maqueira later bragged to police about using the device.
Later, Maqueira showed up at the elementary school, accompanied by their 15-year-old daughter. He tried to convince her to drop the divorce proceedings and return home. She refused.
The tense encounter in the parking lot left Calderin shaken and tearful, co-workers told police. Her supervisor allowed her to leave early, about 9:30 p.m. As she left, Calderin called Vasquez. They chatted briefly until something odd happened. “At 9:38, the call just dropped,” Vasquez told police.
She never came home.
For police detectives, Maqueira’s behavior after Calderin disappeared was baffling.
Maqueira got a television station to back off on a story about her disappearance, threatening to sue. He began flooding her friends with phone calls, bad mouthing the missing woman — at one point, even accosting her friend Guerra outside the police station, demanding to know what she had just told detectives.
