HEMET  (AP) — A California appeals court has refused to overturn the conviction of a man who repeatedly tried to kill a Hemet police officer, likening his zany efforts to those of Wile E. Coyote.

n appellate panel on Monday upheld the 2011 conviction of Nicholas Smit.

Smit received four consecutive life sentences for trying to kill a police detective who was scheduled to testify in his drug trial.

Prosecutors say Smit left nail and gun booby-traps outside the detective’s home and car, rerouted a natural gas line into a police office, set a zip gun to fire at the gate of a gang task force, set several fires and tried to fire a World War II-era rocket at the police station — but it fizzled.
