According to Pierce County deputies, inmate Jimi Hamilton is a problem who won't go away.
"We know that our suspect here was brutal, arrogant," says Pierce County sheriff's spokesman Ed Troyer.
Hamilton's infamy began more than five years ago when he was in Pierce County Jail for bank robbery. While awaiting sentencing, he struck up a love relationship with jail guard Sara Camarillo.
"She was a corrections officer, she wasn't on very long," says Troyer. "We immediately found out what was happening through some ... letters and correspondence between the two."
Hamilton's affair with Camarillo turned into a secret marriage - literally moments before he was sentenced to 14 years in prison for robbery.
"Same trip to the courtroom, they did it in the back room without letting us know 'cause we're going to try to do everything we can to disrupt it - not let it occur," says Troyer.
Meanwhile, he says, Camarillo resigned before Pierce County could fire her.
"The whole thing was a scam of the system," says Troyer.
Now, five years later, Hamilton is serving time in a special offender unit at Monroe. He has a history of infractions within prison, including assaulting custodial staff.
According to the Department of Corrections, he apparently approached an officer there Thursday morning, saying he wanted to file a grievance.
Instead, in front of a dozen witnesses, Hamilton allegedly attacked the officer, punched him in the face and threw him on the floor.
A video camera captured the attack - but there is no audio and no confirmation about what provoked it.
KOMO News tried to find out more from the Monroe officer, who's now home from the hospital, but he would not go on camera.
Meanwhile, the whole case is the reopening of an old wound for Pierce County.
"It doesn't surprise us that they've both reappeared," says Troyer.
Hamilton himself is expected to be formally charged next week. KOMO News could not reach the former jail guard who is now his wife.
