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 into police Wednesday night. Police questioned him about the murder of his wife, 29-year-old Gladys Machado and her two daughters.

A neighbor went inside the home, located on Northwest Fourth Street and 73rd Avenue, at around 2:30 p.m. Tuesday, and found Machado and her two daughters 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."

Machado's daughters were 4 and 8 years old.

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.

Sierra has a record, which includes arrest for drugs, weapons and domestic violence. He was married to Machado, but police will not say if he is a suspect in the murders.

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.

If you have any information on these murders, call Miami-Dade Crime Stoppers at 305-471-TIPS. Remember, you can always remain anonymous, and you may be eligible for a reward.
