Gladys Machado and her two daughters, 4-year-old Daniela Padron and 8-year-old Julia Padron, died on Nov. 10, 2012, at their home in the area of Northwest 73 Avenue and Fourth Street, according to deputies.
Machado had given a neighbor access to the home, and the neighbor followed a putrid smell to a bedroom closet, found their bodies, and called 911 on Nov. 13, 2012, according to deputies.
Deputies arrested Alberto Sierra, then 28, on Nov. 19, 2012. Detective Rosie Cordero-Stutz, now the Miami-Dade Sheriff, talked to reporters about the case after the arrest.
“He used a plastic bag to asphyxiate Gladys,” Cordero-Stutz said. “And after that, he sexually assaulted her.”
