A Maryland couple has been arrested after their 2-month-old daughter died from severe head and brain injuries, according to police and court documents. Oscar Pineda and Katerin Monzon-Alvarado, both 21, face child abuse, assault and reckless endangerment charges. Investigators said the infant had extensive bruising, hemorrhaging and multiple skull fractures. Prosecutors said additional homicide charges could be considered after an autopsy.
The baby, identified as Aida Mikea Monzon Alvarado, was taken to Harbor Hospital after becoming unresponsive. Medical staff were unable to revive her, and she died at the hospital. The allegations remain subject to court proceedings.
According to charging documents, the father offered investigators an explanation involving a supernatural force, while the mother described a possible fall from a bed. Prosecutors argued that the injuries were too extensive to have resulted from a single fall.
Both parents were held without bail after prosecutors characterized them as an extreme flight risk. They are Guatemalan nationals, according to the case information presented in court.

The infant’s death and medical findings
The case concerns Aida Mikea Monzon Alvarado, a 2-month-old girl who was brought to Harbor Hospital on a Wednesday after becoming unresponsive. Police said doctors initially observed suspicious and severe bruising around her eyes and jawline. A later examination found significant head and brain trauma that included frontal lobe hemorrhaging, a subdural hemorrhage and multiple skull fractures.
Hospital staff attempted to treat the child, but they could not revive her. She died at the hospital. The medical findings prompted investigators to examine how the injuries occurred and why treatment was not sought earlier. An autopsy report was still pending, and officials said its findings could affect the charges.
The parents’ accounts to investigators
Charging documents describe different explanations provided by the parents. The father, Oscar Pineda, allegedly told police that the injuries were caused by a supernatural force or by Satan slamming a door on the child. The mother, Katerin Monzon-Alvarado, reportedly said her 2-year-old son often jumped on the bed and that the baby may have fallen onto the floor.
At an ensuing court hearing, a prosecutor argued that the extent of the injuries could not have been caused by one fall from a bed. The statements are allegations contained in the case documents, and the defendants have not been convicted. Investigators are expected to compare the accounts with the medical evidence and the results of the autopsy.
Charges and potential penalties
Both defendants face first- and second-degree child abuse, first- and second-degree assault and reckless endangerment charges. Police said the combined charges carry a maximum possible sentence of 55 years in prison. The case is being handled in Maryland in connection with the infant’s death.
The current charges relate to alleged abuse, assault and endangerment. Authorities said homicide charges could be added depending on the autopsy and the continuing investigation. The allegations must be proven in court, and the charging documents represent the prosecution’s account rather than a final finding of guilt.
The timeline before emergency treatment
According to prosecutors, both parents later acknowledged that they noticed bruising on the infant on Sept. 6. They also said the child began vomiting the following day. Despite those symptoms, the parents did not seek medical treatment until the baby became unresponsive several days later.
The mother initially told police that the child became unresponsive while lying face down on the couple’s bed after being fed. She later brought the infant to the hospital and reportedly described her as freezing and in shock. The timing of the symptoms, the delay in seeking care and the medical findings form key parts of the investigation.
Court status and next investigative steps
Pineda and Monzon-Alvarado were arrested and held without bail. Prosecutors argued that both posed an extreme flight risk, noting that they are Guatemalan nationals. Their detention status was determined during court proceedings following the arrests.
The next major step is the completion of the autopsy, which may clarify the cause and manner of death and determine whether prosecutors pursue homicide charges. Investigators will also continue reviewing medical records, witness statements and the parents’ accounts. Any final determination will come through the court process.
