"They should've let us know so that we can come to peace with what happened," Carter said. "If it wasn't for my aunt reaching out to them and bringing my mom to their attention, we probably wouldn't have known."
The San Joaquin Sheriff's Office will also resurvey the scene where Melton's partial remains were discovered for any further evidence, police said Monday.
After unsuccessful searches of places Shermantine has identified to officials as potential burial sites, the San Joaquin Sherriff's office, along with other law enforcement agencies, had previously considered taking Shermantine to the locations so he could personally identify them. But Moore nixed the idea in fear that Shermantine might attempt to escape.
In the meantime, Carter said she and her family are bitter about the way authorities have handled the homicide investigation.
"I don't know what else to say," Carter said. "I want an apology for everything we've been through, for them not notifying my family after they positively identified her and I want to make sure this doesn't ever happen again."
