Alameda County sheriff's spokesman Sgt. J.D. Nelson said a doctor decided that Giselle Esteban was not well enough to attend court on Wednesday.Esteban's attorney Andrea Auer told the judge during Wednesday's brief hearing that she'll request bail for the 27-year-old Esteban at the next scheduled court date on Oct. 24.Prosecutors charged Esteban in the death of 26-year-old San Diego native Michelle Le. Police believe Esteban, a former friend of Le's from their days at Mt. Carmel High School, attacked Le in a Hayward parking garage on May 27.Le's remains were discovered on Sept. 17, several miles away from the hospital where she was last seen. Police said Le had her car keys and cellphone when she went to her car, but left the rest of her belongings.Police said Le's instructor reported her missing when she never returned to class.Authorities said the killing may have stemmed from Esteban's jealousy of her former friend.Esteban told Bay Area TV station KGO in June that she hated Le because Le was friends with the father of Esteban's 5-year-old daughter. But Esteban denied having anything to do with Le's disappearance.About 200 people attended an Oakland candlelight vigil to remember Le on Tuesday.
