After the escape of three inmates launched an eight-day manhunt, Orange County, California, officials shared details on the efforts that led to their recapture at media briefings on Monday.

Orange County District Attorney Tony Rackauckas said more than 60 search and arrest warrants were made related to the investigation, including a man who was suspected of smuggling tools into the jail. Loc Ba Nguyen, who was not an employee or inmate at the jail, was arrested and said to face charges in relation to the Jan. 22 crime, prosecutors said.

Bac Duong, Jonathan Tieu, 20, and Hossein Nayeri, 37, escaped from the Orange County Central Men’s Jail in Santa Ana on Jan. 22, in what authorities called an elaborate plan. The inmates allegedly cut through a steel grate, half-inch steel bars and plumbing tunnels before making their way to an unsecured part of the jail’s roof and using makeshift ropes to rappel several floors to the ground.

Rackauckas also mentioned there was insufficient evidence to charge ESL jail teacher Nooshafarin Ravaghi, who was arrested for allegedly assisting in the escape.

Investigators found Nayeri and Ravaghi had more than a teacher-student relationship, but did not confirm it was a romantic affair, said Rackauckas. He also mentioned letters that were found between the two appeared to have been written by Nayeri not Ravaghi.

Ravaghi was set to be released Monday and expected to remain under Orange County jurisdiction.

Duong was taken into custody on Friday after he walked up to a civilian in Santa Ana and said he wanted to turn himself in. The San Francisco Police Department arrested Tieu and Nayeri on Saturday after receiving a tip from an observant witness, Orange County Sheriff Sandra Hutchens said.

Nayeri had been in custody since September 2014, Tieu since October 2013 and Duong since December.
