CALIFORNIA (CBS) -- Hayward, California police announced Wednesday that they made an arrest in the case of missing nursing student Michelle Le.
Alameda Police arrested Giselle Esteban, a high school friend of Le's, Wednesday in Union City on a murder charge.aEsteban was named a person of interest in the case by investigators back in June.
The 26-year-old Le disappeared on May 27 from Kaiser Permanente Hayward Medical Center during a nursing class that evening.
Her disappearance led to a massive search organized by her family, who has also offered a $100,000 reward for her return or for information on her whereabouts.
Police had classified the case as a homicide back in June but her family held out hope for her safe return.
Esteban had been reported saying that she openly hated Le for stealing her boyfriend, but had nothing to do with Le's disappearance. Investigators had interviewed her multiple times since Le was reported missing.
Lt. Roger Keener with the Criminal Investigations Bureau Manager said this at a press conference:
"This morning one of those missions has been successfully completely with the arrest of a suspect we believe through a thorough investigation is responsible for Michelle's demise. Yesterday a judge from the Alameda County Superiors Court authorized a probable cause arrest warrant in the name of Giselle Esteban for the crime of murder. Esteban was arrested this morning at about 10 a.m. as she was leaving her residence in Union City and her arrest was met with no resistance. On May 27th of this year a 26-year-old nursing student was at Hayward Kaiser Hospital as part of her curriculum at about 7 p.m. She told a fellow student that she was going to go to her car during their break. Michelle was seen walking to her car however she never returned to class.
"We immediately launched a search for her including an attempted to locate Michelle through cell phone and cell tower analysis at about 9 a.m. The next day we found Michelle's car lock and secured on Ponderosa Drive at bout one half mile from where her vehicle had previously been parked at Kaiser Hospital.
"Some of the compelling evidence leading to Esteban's arrest for the murder of Michelle Lee are blood stains located inside Michelle's car have been analyzed in a crime lab and have been confirmed that Michelle was the source of those blood stains. Security camera footage at the Kaiser hospital where Michelle's car had been reveals that Esteban was present both before and after Michelle's disappearance. Physical evidence has identified that Esteban had been inside the vehicle cell phone records and cell tower activations show that Michelle's phone and Esteban's phone traveled on a similar path from the Kaiser Hospital area toward locations in Alameda County immediately after Michelle's disappearance. A search warrant was served on Esteban's residence on May 29th among the items recovered was a pair of athletic shoes that Esteban requested to wear. Michelle's DNA was recovered from one of Esteban's shoes taken during a search warrant at Esteban's home.
"We will not consider this investigation complete until Michelle is found."
