Man Charged With Murdering 5-Year-Old Boy Found in Suitcase Nearly a Decade Ago

Alberto Sierra has been arrested and charged with murdering 5-year-old Jeremiah Oliver, whose remains were found in a suitcase in 2014, nearly a year after he went missing.
Sierra was the boyfriend of Jeremiah's mother at the time of Jeremiah's disappearance and death.
Jeremiah's family was under state supervision due to reports of neglect and abuse, but case workers missed multiple visits with the family.
Jeremiah's mother pleaded guilty to assault and battery of her children and was sentenced to seven years in prison.
Jeremiah's death led to major reforms in Massachusetts' child welfare system.
