Giselle Esteban Convicted in Murder of Michelle Le

On October 29, 2012, a jury found Giselle Diwag Esteban guilty of first degree murder for the killing of 26-year-old nursing student Michelle Le. DDA Butch Ford represented the People in court.

District Attorney Nancy E. O’Malley stated, “I am pleased the perpetrator of this heinous, calculated crime has been brought to justice. I hope today’s verdict will help the family and friends of Ms. Le to continue the long process towards healing following this tragic and senseless crime.”

Defendant Esteban and the victim, Michelle Le, grew up together in San Diego. Both moved to the Bay Area for college and it was there they met and befriended Scott Marasigan. Defendant Esteban and Mr. Marasigan began dating. For years, the couple had an on/off relationship and eventually had a child together. Ms. Le had a close platonic friendship with Mr. Marasigan, but Defendant Esteban became convinced that the two were having an affair.

In the months leading up to Ms. Le’s murder, defendant Esteban’s hatred towards Ms. Le intensified. Mr. Marasigan recorded multiple chilling conversations with defendant Esteban, including one in November 2010 where she threatened Mr. Marasigan and Ms. Le, saying “You deserve to die for your lies, as does she." Defendant Esteban stalked Ms. Le, and took many steps to track her down.

On May 27, 2011, around 7p.m, Ms. Le left her class at Kaiser Hospital Hayward to get something from her car. Defendant Esteban waited for Ms. Le, and murdered her. Defendant Esteban then drove Ms. Le’s car to a remote location in Sunol where she dumped the body of Ms. Le and concealed it with brush. Ms. Le’s car was found the following morning, half a mile from where it was last seen at Kaiser Hospital. DNA analysis later confirmed the bloodstains and hair found at the scene of the crime and in the car matched the victim.

Approximately five months after her disappearance, Ms. Le’s decomposed body was discovered off a country road between Sunol and Pleasanton. Her identity was established by dental records.
