In 2002, Robinson stood trial in Kansas for the murders of Trouten, Lewicka and Stasi, along with multiple lesser charges. After the longest criminal trial in Kansas history, he was convicted on all counts; he received the death sentence for the murders of Trouten and Lewicka, and life imprisonment for Stasi's (because she was killed before Kansas reinstated the death penalty). He also received a five-to-20-year prison sentence for "interfering with the parental custody" of Stasi's baby, 20½ years for kidnapping Trouten, and seven months for theft.
