Two WSU students were arrested Wednesday for their alleged roles in the attack on David Warner, and Pullman detectives were looking for two others thought to have taken part in the crime.
The men, 22-year-old Robert D. Bean and 22-year-old Matt Cabanos-Soriano, had agreed to turn themselves in Thursday night in Mukilteo, where Bean lives. But police say neither Bean nor Cabanos-Soriano showed up, and now detectives are asking for help to track them down.
Neither is believed to be a WSU student, but have a Pullman connection as acquaintances of Joshua Nantz and Madeline Fouts. Nantz and Fouts were arrested Wednesday in Pullman after detectives followed up on an anonymous tip received late last week.
Warner remains in critical condition at a Spokane hospital. Police say he was beaten about 2 a.m. on March 30 while intervening in a fight between an acquaintance and a group of college-age people.
On Tuesday, WSU President Elson Floyd donated $10,000 to the reward fund to help catch the assailants.
