In December 2011, Sierra was pregnant with her third child, and apparently eager for him to join older brothers Jaydyn and Dontrell, who she hadn’t seen for five months by that time.
“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...” she wrote in a Facebook posting.
Calvin’s story, on the other hand, changed several times.
At first, Calvin told police the baby was with his parents in Pompano Beach. But Annie Melvin said she hadn’t seen the boy since he was 2 months old.
Calvin then told police that Sierra gave the baby to one of her family members, who was visiting from New Jersey.
“Melvin stated he was upset, but accepted Sierra’s explanation,” the detectives wrote in the report.
Calvin told police he had a bad feeling.
“ ‘I don’t want that f------ baby anymore,’’’ Melvin quoted Sierra as saying. He also described his girlfriend as “a psycho who cuts herself.”
With Melvin’s map and the couple’s statements, investigators were able to get a search warrant for the Hallandale Beach rental home. On Jan. 11, with the help of a cadaver dog, the delicate remains — about 90 percent of the skeleton — were dug up.
Forensic anthropologist Heather Walsh-Haney told police that there was no evidence of blunt trauma to the bones before they were buried.
However, at some point during the search and recovery, there was postmortem blunt trauma to the cranium, she advised.
Ed Hoeg, Melvin’s attorney, said last week that he would be looking into whether that compromises the case against his client.
“If there is only trauma afterward, did the damage destroy evidence?” he said.
Dohn Williams Jr., Sierra’s attorney, said Tuesday he hadn’t yet seen the discovery, but would decide how to proceed after studying the report.
