LOS ANGELES – An unemployed man who prosecutors said wanted to handcuff and rape filmmaker Steven Spielberg was convicted Wednesday of stalking the director. The jury found Jonathan Norman, 31, guilty of stalking after deliberating for 3 1/2 hours Tuesday but withheld announcing its verdict until Wednesday. Norman showed no reaction as the verdict was announced. Superior Court Judge Steven Suzukawa set sentencing for April 22. Norman could face 25 years to life in jail under California’s “three strikes” law. Prosecutors had said Norman was sexually obsessed with Spielberg and went to the filmmaker’s gated estate on four different occasions.
