All four suspects in the assault on WSU instructor David Warner have now been arrested and charged.
At 9:20 Friday morning, 22-year-old Robert D. Bean turned himself in at the Whitman County Sheriff's office in Colfax. He was arrested there by Pullman detectives and booked into Whitman County Jail on a first-degree assault charge.
Pullman police also arrested 22-year-old John "Matt" Cabanos-Soriano Friday morning. Cabanos-Soriano appeared at the Pullman Police Department at about 2:20 a.m. and was immediately taken into custody and booked on first-degree assault charges.
Cabanos-Soriano is one of two suspects who were supposed to turn themselves in Thursday night, but failed to appear.
Joshua Nantz, 23, faces a first-degree assault charge from the incident outside a Pullman bar on March 30. He is one of three suspects accused of hitting Dr. David Warner, who is continuing his recovery at Sacred Heart Medical Center. The fourth suspect, Madeline Fouts, is charged with rendering criminal assistance and lying to police.
Family members said Thursday morning Warner is conscious and alert. He has been upgraded to serious condition.
Meanwhile, at his first appearance in Whitman County Superior Court, Nantz, who does not have a criminal history and who his attorney said isn't a flight risk, was released on his own recognizance.
Although all suspects have been arrested, the investigation continues with Pullman Police detectives interviewing known witnesses and seeking additional witnesses and personal video of the assault.
Investigators ask that anyone who saw the assault to call Pullman Police.
