Reiser is expected to be sentenced Friday.
Reiser was convicted of first-degree murder in April for the killing of his estranged wife Nina. She disappeared after dropping off their two children in September, 2006, at Reiser's Oakland Hills home.
Last month, Reiser led police to Nina's body, buried in an East Bay park, in exchange for reducing his conviction to second-degree murder.
A first-degree murder conviction carries a sentence of 25 years to life, second-degree murder is 15 years to life.
