Miami-Dade police questioned the husband of a woman who, along with her two daughters, was found murdered in her home Tuesday.

Police questioned Alberto Sierra late Wednesday and released him Thursday morning. He was not arrested and has not been named a suspect in his wife's murder.

According to Miami-Dade Police, a family friend discovered the bodies of Gladys Del Carmen Sierra, 29, and her daughters, Julia Padrino, 6, and Daniela Padrino, 4, in a home in the 7300 block of NW 4th Street on Tuesday afternoon.

The woman who found the bodies told Local 10 that Sierra was her landlord.

Sierra and Gladys had been married for a year. He has been convicted several times, including for selling cocaine and possession of a firearm.

Last year, Sierra was charged with possession of a firearm by a convicted felon. He was released from jail in June.

Court records show a year before the couple married, Sierra was accused of assaulting Gladys. A stay away order was issued in court.

According to court records, Michael Padrino, Gladys Sierra's former husband, asked a judge for custody of his two daughters last year, but was denied.

A principal at Julia Padrino's former elementary school said the girl told her teacher that her stepfather had bit her. The teacher notified the Department of Children and Families, which confirmed an investigation was started on the family.

Police said Gladys Sierra also has a 6-year-old son. The boy is now living with a family member.
