Los Rios Police were alerted of a violent crime occurring on campus on March 10 at 3:09 p.m., according to an email sent out from Los Rios Alert.

The campus was immediately put under a precautionary lockdown, which lasted a little over an hour to investigate the crime of a robbery. Los Rios Police Sgt. Brian Washington said the alleged crime took place in the parking structure.

“Supposedly, another person threatened a person with a gun and took a bike and a cellphone,” Washington said in a phone interview on Monday. “Various juveniles were detained and a search of the campus was conducted for a firearm, no firearm was found.”

Washington said neither the suspect nor the victim are students at Cosumnes River College.

CRC President Ed Bush sent a follow-up email to the CRC community about the lockdown.

“The incident is an important reminder of how vital the work we do is,” Bush said in the email. “Not only in keeping our college safe, but in our commitment to the community surrounding us.”

Bush went on to mention the other lockdowns CRC has endured in the past academic year.

“I also want to acknowledge that it’s been a particularly challenging year for CRC from a public safety perspective,” Bush said. “I am deeply thankful for the health and safety of our students, faculty, and staff, in spite of a number of incidents that have shaken our campus community.”
