A Miami-Dade grand jury on Wednesday indicted a Kendall man accused of murdering his wife and two young stepdaughters.

The indictment on three counts of first-degree murder means prosecutors can pursue the death penalty against Alberto Sierra, 28, for the November slayings of Gladys Machado, 29, and her daughters Julia and Daniela, ages 8 and 4.

Miami-Dade police say Sierra confessed to using a plastic bag to suffocate the victims, whose bodies were found laid out in a bedroom closet of a Flagami-area home. DNA samples taken from Julia’s body matched Sierra, according to court documents.

Prosecutors declined to pursue sexual battery charges against Sierra because the victims were already dead when he allegedly raped the bodies. Instead, Sierra was indicted on two counts of abusing human remains, a second-degree felony.

He was also indicted on kidnapping and armed burglary charges. Sierra’s arraignment is Jan. 10 in front of Miami-Dade Circuit Judge Dennis Murphy.
