SANTA ANA — A La Habra woman accused of killing her infant son by throwing him from the fourth floor of a hospital structure is mentally competent to stand trial, a judge ruled earlier this week.
Sonia Hermosillo, 31, is charged with murder and child abuse after removing a protective helmet from her 7-month-old son, which he wore because of a medical condition, and tossed him from a parking structure at the Children’s Hospital of Orange County on Aug. 22, investigators said. Her attorney had previously argued that she lacked the mental ability to assist in her own defense.
At a mental competency hearing held Monday in Santa Ana Superior Court, “The judge in that case determined she is competent to stand trial,” Orange County District Attorney’s Office spokeswoman Farrah Emami said.
She was ordered to return to court for an arraignment on April 6, officials added.
Noe Medina Jr. died two days after the fall, officials said.
Hermosillo, who police said validated her parking pass before exiting the hospital’s parking structure, was arrested later in the day when she was spotted driving past the hospital as police investigated the scene.
While an officials motive in the case has not been released, Hermosillo’s husband, Noe Medina, has said she suffered from postpartum depression and never accepted their son, who suffered from two treatable medical conditions.
According to county booking records, Hermosillo is being held without bail.
If convicted as charged, she could face up to 50 years to life in state prison.
