Bryan Kohberger's attorneys say their client shouldn't have to pay $27K in restitution ... and, they're set to appear in court in just a few minutes to argue the case. The convicted murderer's lawyers are back in court Wednesday ... claiming Kohberger shouldn't have to pay up -- because the families of his victims already received tons of money from GoFundMe accounts they set up for travel and accommodation expenses. If you don't know, Kohberger already agreed to pay $250K in criminal fines plus another $80K to be split four ways among the families of Kaylee Goncalves, Madison Mogen, Ethan Chapin, and Xana Kernodle. His lawyers aren't contesting these payments ... they're contesting an additional $27K -- $20K for Kaylee's family and $7K for Madison's mom -- to pay for the aforementioned travel expenses. As you know ... Kohberger pled guilty to the four murders over the summer to avoid the death penalty -- a controversial plea deal decried by many, including the victims' families. Kohberger's been locked up in Idaho Maximum Security Institution in Kuna -- a small town southwest of Boise -- since pleading guilty ... and, it hasn't exactly been smooth sailing for the guy, who has complained to the state about receiving taunts from fellow inmates. Besides the alleged taunts, Kohberger's life behind bars has been exceedingly mundane. He's confined to his cell for the most part ... getting just one hour of rec time a day.
