About seven months ago, he came back home and an investigation was launched. 

"On March 11, 2022—nearly two years after being reported missing—Ramirez inexplicably returned home," sheriff's officials said in a press release.

They said "a thorough investigation" led them to Olivares, whom they identified as an employee at Alice Birney Waldorf-Inspired K-8 School in Sacramento. She's listed as a second grade teacher on the school's website.

In a statement to KTVU, the Sacramento City Unified School District (SCUSD) confirmed that Olivares currently remained a district employee. 

The statement went on to say, "The charges filed are for acts unrelated to the employee’s assigned duties. The employee has been placed on administrative leave pending the outcome of a District investigation." A spokesman also described the case as a "personal matter" for Olivares. 

Olivares was set to appear in Sacramento County Superior Court for her arraignment on Monday afternoon. 

Investigators asked anyone with information about this case to contact the Rancho Cordova Police Department at (916) 362-5115. Tips can also be left anonymously at or by calling (916) 874-TIPS (8477).
