Le, 26, went missing on May 27 during a break from her clinical rotation at Kaiser Permanente Hayward Medical Center on Sleeping Hollow Avenue.
Last Friday, her family, friends and sorority sisters held a fundraiser at a Hayward restaurant in which 20 percent of the sales were donated toward the reward fund.
Her family continues to hold out hope despite the fact that Hayward police classified Le's disappearance as a homicide. Although the family has been working with Hayward police and the FBI, it hired a private investigator last month to independently conduct a parallel investigation.
"Our family has spent the last 45 days saving money to reach this amount," Michelle's brother, Michael Le, said in a statement released by the family today. "We're hoping this will motivate someone to find it in themselves to step forward; we just want her home with us."
The family plans to distribute fliers on Wednesday at 26231 Mission Blvd. in Hayward. Search parties are also being organized for Friday and Saturday.
Volunteers will meet at 25350 Cypress Ave. in Hayward at 8 a.m. on both days.
