SANDPOINT – A northern Idaho prosecutor is seeking the death penalty in a case involving a Washington state man suspected of repeatedly stabbing a cab driver and letting him slowly bleed to death.

The Bonner County Daily Bee reported Bonner County Prosecutor Louis Marshall filed the notice Tuesday, making Jacob Corban Coleman’s defense aware of the state’s plans to prove aggravating factors in the killing of 22-year-old Gagandeep Singh.

Authorities believe Singh picked up Coleman on Aug. 28, 2017, but stopped the cab in Kootenai, Idaho, when he suspected Coleman didn’t have a destination. Police said Coleman then stabbed Singh.

Coleman pleaded not guilty to first-degree murder in November.

Coleman’s trial is scheduled for April.
