Police in California have arrested a Hispanic woman they said is suspected of killing a nursing student who was last seen in a hospital parking garage months ago

Giselle Esteban, 27, was arrested in Union City, California, Lt. Roger Keener of the Hayward Police Department said. Evidence - including blood stains, security camera footage, cell phone records and DNA found on a shoe - led to Esteban's arrest for the murder of Michelle Le. Esteban was arraigned and listed as an inmate in an Alameda County jail without bail. Le, a 26-year-old nursing student, disappeared on May 27, 2011 after telling classmates at a hospital in Hawyard, California, that she was going to get something from her car. She never returned and the abandoned vehicle was later found about a half-mile away. Investigators searched Esteban's house shortly after Le disappeared. As part of that search they found Le's DNA on one of Esteban's shoes. Police have classified the case as a homicide, but her family has held out hope for her safe return. Le's family has offered a $100,000 reward for her return or for information on her whereabouts.
