Husband questioned and released in triple murder

MIAMI (WSVN) -- The estranged husband of a woman found murdered along with her daughters has been interviewed by police and released without facing any charges.

Alberto Sierra, 28, turned himself over to police Wednesday night. Police questioned him about the murder of his wife, 29-year-old Gladys Machado and her two daughters. Police released him, emphasizing he was not a suspect and they are working many other leads in the case. However, court records revealed a tumultuous relationship between Sierra and Machado.

Court records revealed Sierra does have a record, which includes arrests for drugs, weapons and domestic violence.

A neighbor discovered Machado's body inside her home, located on Northwest Fourth Street and 73rd Avenue, at around 2:30 p.m. Tuesday. She and her two daughters,4 and 8 years old, were found dead inside a closet. "The neighbor, who was inside the residence, noticed a foul odor that she did not recognize," said Miami-Dade Police Detective Roy Rutland. "She then went and searched the home. Inside the closet, this neighbor found the body of a mother and that mother's two daughters."

A friend said she last spoke to Machado on Friday, the same night Machado posted a status on her Facebook which read: "Where this road goes no one knows."

Machado worked at the registrar at Beauty Schools of America. "In respect for the family, we send out condolences. We are deeply saddened," said coworker Jeff Gonzales.

Machado has a son from a previous relationship. The boy was found safe in another location.

At this time, police have not charged anyone for the murders.
