Police believe that the trio;

“slipped behind beds inside the jail, then disappeared into a hole in a wall before navigating through the jail’s plumbing system and cutting through half-inch steel bars.After making it to the roof, the men rappelled down four stories using spare cloth and bedsheets and fled.”

Authorities report this is the first time an inmate has escaped from this facility in over 30 years. At this time it remains unclear if the men received help in their escape, however police are offering a $50,000 reward for any information on the men’s whereabouts. They were last seen wearing orange jumpsuits and are assumed to be armed.

Tieu had been held since October 2013 on $1 million bond and is being charged with murder that was possibly gang-related. Duong, who has multiple convictions, was being held without bail since last month in connection with attempted murder.

Nayeri, along with three other men has been accused of kidnapping and torturing a California marijuana dispensary owner back in 2012. According to police, they drove the owner to the desert, where they believed he had hidden money, and severed his penis.
