Schoenlein apparently scaled one razor fence, but suffered deep cuts on his back, leg and hand as he attempted to get over a second one. OCCC officials found torn pieces of clothing and a pool of blood at a fence on the makai side of the Kalihi facility.

Schoenlein was taken to The Queen's Medical Center for treatment. Because of the severity of his injuries, he was taken for a magnetic resonance imaging exam at about 9 p.m. Tuesday, said Mike Gaede, spokesman with the Department of Public Safety.

"At that point you can't have metal on so they took the belly chain, handcuffs off him. But he was still in leg irons," Gaede said.

When he returned to his room, Schoenlein said he wanted to take a shower, Gaede said. While in the shower with a corrections officer on guard, Schoenlein attacked the guard and the two fell into the hallway.

Gaede said three men who were in the hallway came to the guard's aid and subdued Schoenlein. No one was seriously injured in the scuffle, he said.

Gaede said Schoenlein probably wouldn't have gotten too far because of the leg irons and the severity of his injuries. Extra security has been placed in Schoenlein's room and he was expected to spend another day in the hospital before returning to OCCC, Gaede said.

Schoenlein faces two attempted escape charges, as well as an assault charge, Gaede said.

"He just guaranteed himself a little more time than his original charges," Gaede said.
