OROVILLE, Calif. -

The teenager accused of the drunk driving death of a Chico State student, pleaded not guilty in court Wednesday.   Riley Hoover, 19, now faces an additional felony drug charge.

In addition to the series of charges Hoover originally faced for the deadly collision, the Butte County District Attorney's Office has added an additional drug charge related to the manufacturing of butane honey oil.

Investigators said late on the night of Sunday, September 22, Hoover's car struck Chico State nursing student Kristina Chesterman as she was riding her bike home from the library.  The 21-year-old died at the hospital several days later.

The Butte County District Attorney Mike Ramsey said Hoover's blood alcohol level may have been as high as .30 at the time of the collision, which is more than three times the legal limit for driving.

Chico Police said Hoover had 40 ounces of hash inside his car.  That led to a search warrant in the foothills of Berry Creek where four other suspects were arrested on drug charges.

In court Wednesday, KRCR News Channel 7 reporter Tyler May was allowed to shoot video of Hoover for the first time since the deadly collision.  Hoover's hair is shorter than his previous mugshot obtained by KRCR News Channel 7 from a previous drug trafficking arrest in Ohio.

Hoover remains in the Butte County Jail.  He's originally from Ohio.  Prosecutors said Hoover recently moved to Chico to make money off the marijuana trade.
