Police in Idaho have arrested a third person in connection with the escape of a prisoner.

Tia Garcia, 27, of Twin Falls is charged with aiding and abetting escape in connection with the escape of Skylar Meade earlier this month.

The Boise Police Department say Garcia had knowledge and was involved in the planning and execution of the escape.

Skylar Meade and Nicholas Umphenour were taken into custody in Twin Falls, Idaho, according to police.

Umphenour was wanted on two charges of aggravated battery against law enforcement and one charge of aiding and abetting, in connection with Meade's prison break, which resulted in the shootings of three officers.

Authorities allege Umphenour helped facilitate Meade's "brazen" and "coordinated" escape from a Boise, Idaho, hospital in the middle of the night, where the inmate was taken for treatment for an allegededly self-inflicted injury.

Umphenour is accused of firing on two Idaho Department of Corrections officers during the breakout. A third officer was shot by a responding Boise cop, said police.

The pair of suspects fled in a gray Honda Civic.

They were apprehended a few days later.

Authorities were also investigating two homicides in the nearby counties of Nez Perce and Clearwater for a possible connection to the two men.

Meade was serving a 20-year prison sentence for aggravated battery on a law enforcement officer with a firearm enhancement and was previously convicted of drug charges, grand theft and introduction of contraband into a correctional facility when he escaped, police said.

He had been locked up since October 2016 and his sentence was set to end in October 2036.

Umphenour and Meade had met at the Idaho Maximum Security Institution. Both have ties to the Aryan Nations white supremacist group, investigators said.

Boise Police say they worked with the Ada County Prosecutor's Office to bring charges against Garcia. She was already in custody at the Twin Falls County Jail following her arrest on March 21 for a probation/parole violation.

She is being held without bail. Police did not release more information on what tied her to the escape.

"The Boise Police Department is continuing to work with our law enforcement partners to investigate these criminal acts and we remain dedicated to seeking justice for all victims," said Boise Police Chief Ron Winegar. "We are thankful for the coordination among law enforcement officers and prosecutors across the state of Idaho, who helped bring this dangerous situation to an end."
