Letter: A jury convicted the man who killed Officer Tim Huffman of negligent homicide. It wasn't enough. For one year and nine months, Jorge Espinoza has been a free man, and Department of Public Safety Officer Tim Huffman has been in his grave. Espinoza caused Huffman's death in an accident near Yuma on May 6, 2013. Last week, a jury convicted Espinoza of negligent homicide instead of the initial charge of second-degree murder. We were victims of the accident that Huffman responded to.
