MARTINEZ — A 19-year-old Berkeley man pleaded not guilty today to killing a Danville teen during an attempted robbery in 2009.

Prosecutors say Walter Bell fatally shot Rylan Fuchs, 17, outside the boy's family home while trying to rob the Fuchs of marijuana on Jan. 20, 2009.

Bell, who was charged 11 months after the homicide, told investigators that the gunfire was accidental.
