A former American River College student was arrested earlier today in connection with the violent sexual assault that occurred Tuesday in the Subway sandwich shop near campus where he worked.

The suspect, Kenneth Chandler Anderson, 22, last attended ARC in the Spring 2011 semester and was a psychology major.

Anderson referenced the attack on his Tumblr page saying “I’m worried about my coworker and how she is doing (because) I haven’t heard from her, the cops aren’t talking about the investigation, I’m worried about my safety.”

Sacramento Sheriff’s Detectives arrested Anderson who, according to a media release, was booked “into the Sacramento County Main Jail on four felony and one misdemeanor charges related to the brutal attack.”

The sketches of the serial rapist bear a “striking resemblance” to Anderson, said Sgt. Lisa Bowman, the Sheriff’s spokesperson.

The serial rapist has been attacking women for the last few months near campus and along the I-80 corridor, with the most recent attack occurring Jan. 8.

The sheriff’s department requested a comparison of Anderson’s DNA and that of the serial rapist due to the physical similarities and the way in which the attacks occurred.

According to Bowman, all the victim’s coworkers were interviewed, and based on Anderson’s appearance and the description given to police by the victim, he was questioned.

Daniel Romandia, 22, a journalism major at ARC, attended Mira Loma High School with Anderson and said he knew him “very well.”

Romandia describes Anderson as being very “cocky” and “full of himself,” saying, “he thought he was smarter, like he was above people,” and that it often put people off.

He also said that Anderson was teased for being overweight and having asthma and didn’t have many girlfriends.

Romandia said that althought he did see the sketches of the previous rape attacks, he “never made the connection.”

Now comparing Anderson’s mug shot and the sketches he said, “they do look like him.”

Anderson is currently in custody and being held on a $1 million bail. Anyone with information concerning the rape at the Auburn Boulevard Subway or the I-80 rapes is encouraged to contact the Sheriff’s Department at (916) 874-5070.
