EXCLUSIVE: Patricia Arquette and James Van Der Beek Hit a Wall During a College Rape Case on 'CSI: Cyber'

Rob Estes guest stars as a university athletic director in Sunday's new episode.

The CSI: Cyber team is heading back to college to investigate a sexual assault case that may unravel the school's athletic department for good.

In Sunday’s brand-new episode, titled “iWitness,” FBI Special Agent Avery Ryan (Patricia Arquette) and FBI Agent Elijah Mundo (James Van Der Beek) pay a visit to Paxton University’s athletic director Julian Perkins (guest star Rob Estes) to gather intel.

They suspect one of the members of the crew team “is a rapist and a murderer,” as Ryan so eloquently puts it. But one crew team member isn’t happy about Ryan and Mundo’s unexpected visit, mouthing off to the FBI agents before getting shut down.

“This isn’t the first time one of my athletes have been wrongly accused of sexual assault. These lies ruin reputations,” Perkins tells the pair.

“Fewer than 10 percent of all rape accusations are false,” Ryan tries to reason, but the athletic director isn’t about to leave his student-athletes high and dry.

“That statistic, Agent Ryan, has nothing to do with these fine young men. Not one of them is capable of rape or murder,” he says, before shutting down any possible search of his crew team’s phones, laptops or other mobile devices.

Back in March, Arquette dropped by the ET stage to dish on the timely CBS procedural, which centers on cyber-based crime.

"It's not just our phones," Arquette said of cyber safety. "It's the way whole corporations work with emails, our whole banking systems, airplanes have Wi-Fi, cars have Wi-Fi, coffee makers. You're going to pick up some tips [from CSI: Cyber] along the way about how to be a little more careful."
