A state-supervised sexually violent predator vanished after his ankle GPS sent a 3:30 a.m. “tamper mode” alert at a San Diego worksite, triggering an urgent manhunt and public warnings, officials said.

Case spotlights strengths and weak points of electronic monitoring in high-risk releases.

What Authorities Say Happened

San Diego County Sheriff’s Office officials said the GPS worn by Merle Wakefield, 69, alerted to “tamper mode” at about 3:30 a.m. while he was working in Rancho Bernardo on September 25, 2026. The Sheriff’s Office said Wakefield is supervised by Liberty Healthcare under California’s Conditional Release Program. Deputies issued a wanted notice and asked people to call 911 right away if they spot him, and not to approach under any circumstance.

News accounts based on the Sheriff’s Office statement report that Liberty Healthcare personnel responded to the scene and found the GPS device had been removed, and Wakefield was not there. Local coverage placed the worksite at an Amazon processing facility in Rancho Bernardo, which gave investigators a clear last-known location window for the search area. Officials later posted the wanted notice online and on social media to widen the alert to residents across the region.

Where The Search Stands Now

The Sheriff’s Office said Wakefield is wanted for violating terms of his conditional release, which set off a countywide effort to locate him. The department’s online alert and social posts included instructions for the public and noted his status in the state release program. Reporters said deputies canvassed the area and reached out to nearby communities for tips after the early morning alert. Agencies often expand beyond the last-known site to likely travel routes within hours of a confirmed disappearance.

One outlet, citing a law enforcement source, reported Wakefield may have discarded a cell phone in bushes and driven off in a 2018 white Toyota Camry, but officials have not released camera images or plate records to the public that would pin down that detail. The Sheriff’s Office has not posted a full minute-by-minute timeline. That is common during active searches, when releasing partial logs can hinder field work or tip off the person being sought.

Who Is Supervising And Why It Matters

Liberty Healthcare manages day-to-day oversight for certain high-risk releases under California’s Conditional Release Program, while county deputies handle public safety alerts and warrants. That split role is standard in many states. The Sheriff’s Office has documented Wakefield’s conditional release status before and noted his prior temporary housing assignment after his 2024 release, which provides background on his supervision track in the county. The current wanted notice ties his status to a specific violation of release conditions rather than to a new charge.

When a monitor sends a tamper alert, protocol usually calls for the supervising contractor to try contact, respond to the site, and then notify law enforcement. Officials say that sequence occurred here, with Liberty Healthcare staff discovering the device had been removed and alerting authorities, who then issued the public warning and wanted notice. The speed and clarity of these steps can shape risk in the first hours after a person goes missing.

Electronic Monitoring: Useful But Not Foolproof

Electronic monitoring can help track a person’s location and signal when rules are broken. But national research shows the systems can fail in several ways, from strap damage and battery loss to signal gaps and false alarms. Many devices trigger a “master tamper” alert when the strap is cut, stretched, or opened, which is meant to warn supervisors right away and prompt a safety check. Those design choices aim to reduce risk in exactly the kind of high-salience case seen here.

Courts and agencies use electronic monitoring across pretrial release, probation, and parole, often for people judged to be a higher risk to public safety. The Wakefield search underlines a hard truth across politics: technology helps, but people still make or break public safety. Voters on the right worry about repeat crime. Voters on the left worry about program quality and oversight. Both want a system that works and a government that acts fast when it does not.

Public Safety Guidance

Deputies asked anyone who sees Wakefield to avoid contact and call 911 or local law enforcement at once. That advice protects the public and preserves evidence. If you live or work near Rancho Bernardo or along likely travel routes, stay alert to official updates. Do not share unconfirmed tips online. Send information directly to authorities. Quick, accurate tips often make the difference in searches like this, especially in the first days after someone disappears.
