An inmate serving a sentence for killing a Pebble Beach woman in 1982 has been sentenced for murdering a Seaside woman. 62 year old Alfred Powell was convicted last month for the murder of Sandra McGee Steppuhn. Steppuhn had been missing since picking up Powell as a hitchhiker in 1982 until her body was discovered in 2015 by landscapers at a property where Powell once lived. On Friday a judge ordered Powell to an additional 15 years to life.
