“There was no allegation of abuse or neglect of this child in the October 2012 Hotline report,” he went on to say.

“This entire department and every employee is deeply saddened each time we hear about the death of an innocent child,” Wilkins wrote.

Between March 2011 and January 2013, callers to the hotline detailed a naked, shoeless 2-year-old running in the street, and the 11-year-old daughter of Menendez bringing a pornographic magazine to school and drawing male genitalia.

Several callers reported the children as dirty and smelly, with unkempt hair, saying that even if they showered, they had no clean clothes to put on.

An agency was called on to bring fresh clothes and offer the family counseling, and a state investigator told Menendez to “mop the floor with a chemical.”

It was Sierra herself who made the October report about her missing son.

Melvin had an explanation: He had taken Dontrell to live with his parents.

Officers went to the grandparents’ Pompano Beach home to check out the story, but the grandparents said it wasn’t true.

Melvin later offered police a variety of stories about his son’s disappearance.

One was that he had left the boy at a North Miami-Dade fire station — which is legal under the state’s Safe Haven law, though only for about a week after a child’s birth.

Police didn’t believe him.

After interviewing the couple, the Hallandale Beach police began digging in the backyard of a home they had formerly rented. That’s where they found the tiny skeletal remains.

“The medical examiner will be examining the remains,’’ said Hallandale Police Chief Dwayne Flournoy. “DNA testing will be conducted for a positive ID.”

Melvin was arrested on Friday on felony charges of child abuse and misdemeanor obstructing a criminal investigation.

He is being held on $150,000 bond.

Sierra was also arrested on Friday on felony charges of child abuse.

On Monday morning, Sierra met with her lawyer, Broward public defender Dohn Williams, for about 30 minutes at the county jail, where she’s being held on $100,000 bond.

“Given the circumstances, she was in a somber mood,’’ said Williams, who saw Sierra in the morning. “I sense she had been crying.’’

On her Facebook page, Brittney Jasmine Sierra offers the kind of sensible parenting guidance that you might expect from a child-rearing expert — but for the bad grammar.

“Always put your kids first and yourself second because you cant (sic) do no wrong if you follow the right path,’’ she wrote in December 2011.

She was pregnant with her third child — “still waiting for this little boy to come out’’ — but apparently eager for him to join his older brothers, Jaydyn and Dontrell, who she hadn’t seen for five months by then.

“I thank gd (sic) for blessing me with such great bad ass kids but they mean the world to me and woulnt (sic) trade them for anything in this world...”
