HAYWARD, Calif. -- A childhood friend was sentenced to 25-years to life in the first degree murder of nursing student Michelle Le.
Prosecutors allege Giselle Esteban stalked and murdered Le because she blamed the young nurse for ruining her relationship with Scott Marasigan, who is the father of Esteban's daughter.
Le's remains were found in a remote area of a canyon, where GPS tracking showed the cell phones of both Le and Esteban, traveled the night Le disappeared.
The canyon was several miles from the Kaiser Hospital in Hayward, where Le disappeared from on May 27.
The 26-year-old was taking a class at the hospital as part of a nursing program at Samuel Merritt University in Oakland.
She left class during a break around 7 p.m. with car keys in hand, but she never returned.
Le's locked Honda SUV was later found a few blocks away.
Esteban, 27, was arrested September 7 in connection with the case.
Police said they found traces of Le's blood inside the SUV, as well as on one of Esteban's shoes.
Esteban and Le were friends and classmates at Mt. Carmel High School in Rancho Penasquitos. Both ended up in the Bay Area after graduation.
The women were best friends in high school, but had been at odds in recent years over a dispute about a boyfriend.
