Their Baby Died With Skull Fractures. The Father Blamed Satan.

A two-month-old girl was rushed to a Baltimore hospital in the middle of the night. She never left it. Days later, her parents gave police two very different explanations for how she got hurt — and neither one held up.

Just after 1 a.m. on September 9, 2026, Baltimore Police officers responded to MedStar Harbor Hospital after staff pronounced an infant, Aida Mikea Monzon Alvarado, dead. Her mother had brought her in after the baby became unresponsive at home. Two days later, on September 11, homicide detectives arrested both of Aida's parents — 21-year-old Katerin Monzon-Alvarado and 21-year-old Oscar Pineda.

Doctors at the hospital noticed suspicious bruising around the infant's eyes, forehead, and jawline before she died. A subsequent examination found far more serious injuries: frontal lobe hemorrhaging, a subdural hemorrhage, and multiple skull fractures. According to charging documents, both parents later admitted to police that they had noticed the bruising, and that Aida had started vomiting the day after — but neither of them took her to a doctor.

Investigators say the parents each offered a different account of what happened. Pineda told police the injuries were caused by a supernatural force — Satan, in his account — slamming a door on the child. Monzon-Alvarado instead pointed to the couple's 2-year-old son, saying he often jumped on the bed and suggesting the infant may have been hurt that way.

Neither explanation matched the severity of what the autopsy described. Both parents are now charged with first- and second-degree child abuse, first- and second-degree assault, and reckless endangerment — charges that carry a maximum of 55 years. Police say additional homicide charges are still possible, pending the medical examiner's final report.

Monzon-Alvarado and Pineda are both being held at Central Booking in Baltimore. No trial date has been set. The medical examiner's office has not yet released its final, official cause-of-death ruling, and prosecutors are waiting on those results before deciding whether to bring homicide charges against either parent.
