Eureka Police arrested Jonas Randall Semore, 42, on suspicion of homicide today in connection with the death of David Dwayne Ganfield last month. Ganfield, of McKinleyville, was dropped off at Mad River Hospital on April 28 after an apparent assault. He died two days later.

Semore had been wanted by the Sheriff's Office in connection with the homicide.

From the Sheriff's Office:

Semore was detained by the Eureka Police Department. The Eureka Police Department was aware that the Humboldt County Sheriff’s Office considered Semore a person of interest in the homicide investigation of Ganfield. The Eureka Police Department then contacted Humboldt County Sheriff’s Office Detectives and advised them that Semore was detained. The Humboldt County Sheriff’s Detective requested that Semore be placed under arrest for the murder of David Ganfield.

Semore was then placed under arrest by the Eureka Police Department for homicide. Semore was transported to the Humboldt County Correctional Facility where he was booked for homicide and his bail was set at one million dollars.

This homicide investigation is still under investigation by Humboldt County Sheriff’s Office Detectives.
