Four Yakima County jail inmates, including three who earlier attacked corrections officers, are accused of stabbing another inmate in the North Front Street jail.

Yakima County sheriff’s detectives say Pedro Solis, Hector Manuel Hernandez, Guadalupe Gutierrez and Jovanni Collazo-Moreno attacked another inmate in a fourth-floor housing unit on Nov. 9 with homemade knives.

Detectives recently completed their investigation and turned the matter over to prosecutors, said sheriff’s spokesman Casey Schilperoort.

Hernandez, 27, Gutierrez, 33, and Collazo-Moreno, 21, were among five inmates previously charged with prison riot and custodial assault on allegations that they attacked corrections officers at the jail on Oct. 31, according to court documents.

Inmates in the unit were being called out of their cells for medication around 3:45 p.m., according to a probable cause affidavit. The four inmates were in the common area of the pod at the time when the victim was called over to pick up medications, and corrections officers said the four went back to their cells and came out and attacked him, the affidavit said.

Corrections officers stopped the attack, which left the victim with multiple puncture wounds. A search of the suspects’ cells found two sharpened pieces of steel reinforcing bars that had been taken out of the walls between two cells, the affidavit said.

The damaged wall had been concealed with tissues, the affidavit said. Corrections officials estimate the damage at more than $750.

Authorities say the injured inmate, who is awaiting trial on charges of indecent liberties, second-degree assault and first-degree child rape, declined to press charges in the attack.

The four are being held on suspicion of prison riot, malicious mischief and weapons possession as a prisoner.

Solis, 19, who is awaiting trial on a first-degree murder charge, had his bail set at $1 million by Yakima County Superior Court Judge Richard Bartheld during a Wednesday hearing. Hernandez’s bail was set at $100,000, while Gutierrez and Collazo-Moreno had bail set at $50,000 and $25,000 respectively.
