The Delhi couple accused of causing the death of a 2-year-old child are awaiting arraignment in Merced County, but only one of them will be facing a murder charge.

Kalena Marie Olson, 22, of Delhi and Sergio Angel Zamora, 23, of Delhi were arrested in Turlock on Aug. 16 on the suspicion of murder for the death of 2-year-old Hennessy Fagin. However, the Merced County District Attorney’s Office has opted to only charge Zamora with murder.

Olson is facing two felony charges of child endangerment, one for Hennessy and one for her 3-year-old sister. Zamora is charged with murder and assaulting a child causing death, according to the district attorney’s office.

On April 21, the Merced County Sheriff’s Department was summoned to a residence in the 9600 block of Hillside Drive in Hilmar for a report of a deceased child.

Merced County Pathologist Dr. Mark A. Super ruled the cause of death was likely from suffocation and stated the child’s sudden death “paints a picture of a battered child.”

Merced County Sheriff’s spokesman Deputy Delray Shelton said both children had similar injuries, but that the 2-year-old’s proved fatal. The 3-year-old was put into the care of Child Protective Services as the investigation progressed.

Early on into the investigation detectives charged Olson with felony child abuse and booked her into the Merced County Jail. A similar warrant was issued for Zamora, but he could not be located, Shelton said. Olson was later released without charges officially being filed as the investigation continued.

The arrest warrants for the pair were issued recently after the pathology testing was completed.

Law enforcement received information the pair were staying at a home on South Avenue in Turlock and surrounded the residence on Aug. 16. Zamora tried to evade capture by running from the home, but he was apprehended after a short foot pursuit. Olson surrendered herself to police custody about 10 minutes after Zamora tried to flee.

The criminal complaint filed in the case states the two children were placed into “circumstances likely to produce great bodily harm or death” from Jan. 1 to April 21.

Zamora could be facing a life sentence if convicted. Olson could be sentenced to the maximum of eight years if she is found guilty.

Both Olson and Zamora are being held at the Merced County Jail. Olson has a bail of $200,000 and Zamora has a bail of $1.1 million, according to jail records.

The couple is set for an arraignment on Sept. 3.
