The Merced County Sheriff’s Office is working with local, state, and federal law enforcement agencies to catch six men who escaped from the county’s downtown Merced jail.

The U.S. Marshals Service set up a tip line and is offering rewards of up to $5,000 per escapee for information leading to their arrests.

Anyone with information is asked to call 1-877-WANTED-2 (1-877-926-8332) or visit the following link: https://www.usmarshals.gov/tips/index.html. Tipsters can remain anonymous.

Escapees Considered Armed and Dangerous

All six escapees should be considered armed and dangerous, the sheriff’s office said.

Jail staff noticed the missing inmates sometime around midnight Saturday.

“A preliminary investigation has determined that the inmates were able to gain access to the roof of the facility and utilize a homemade rope to scale down the side of the jail,” the sheriff’s office said.

Anyone who spots the fugitives is asked not to approach them and immediately call 911.
