UPDATE: Arraignment for Murder Suspect in Missing Nursing Student Case Postponed Due to Medical Issues

The arraignment for a Union City woman facing a murder charge in the case of missing nursing student Michelle Le has been postponed due to medical issues, according to an Alameda County Superior Court judge.

Giselle Diwag Esteban, 27, was originally scheduled for arraignment on murder charges at 2 p.m. Thursday.

According to Judge Gary Picetti, Esteban is currently in the care of medical specialists, possibly related to her pregnancy. Media reports announced yesterday that Esteban may be as much as seven months pregnant. She is the mother of a 5-year-old; the father of that child requested and was issued a restraining order against Esteban three days before Le went missing.

NBC San Diego reports the defendant was rushed to the hospital earlier today.

The case has been postponed to Friday at 2 p.m. at the Hayward Hall of Justice, according to Picetti. However, the judge added Esteban would not appear in court until cleared by doctors. 

The Alameda County District Attorney’s Office filed murder charges against Esteban in the death of Michelle Le Wednesday morning.

Esteban was arrested just before 10 a.m. Wednesday outside of her home at 35530 Monterra Terrace in the Monte Vista neighborhood of Union City, Hayward police said.

Police believe Esteban is the lone suspect in the disappearance of 26-year-old Le. The missing San Mateo resident was last seen leaving Hayward Kaiser hospital, where she was attending clinical rotations as a nursing student, around 7 p.m. on May 27.

Le had told classmates she was picking something up from her car, which was parked inside the hospital's parking garage, but she never returned.

On Wednesday, police said an investigation that included numerous sources of compelling evidence has led them to believe Esteban to be "responsible for Michelle's demise.” Read more about the arrest and investigation .

Le's body has not been found. Neither has any murder weapon. There are no known witnesses in the case.

However, Alameda County Deputy District Attorney Michael Nieto told Patch on Thursday afternoon that prosecutors have enough evidence to take the case to trial.

"We wouldn't have filed the charges if we didn't think there was evidence beyond a reasonable doubt," said Nieto.

Patch will update this report once details are made available.
