Investigators in Santa Rosa have released the identities of a family found fatally shot in a home earlier this month but have yet to describe any motive. Police are still piecing together the case of the four discovered on Jan. 8 in the 200 block of Monarch Court. The coroner has identified two men and two women — Clive Guth, 67, Donna Guth, also 67, Raena Guth, 33; and, Cameron Guth, 28. Donna and Clive Guth were formerly married, and Raena and Cameron were their biological children, according to Santa Rosa police. Officers were originally sent to the location on a welfare check for residents who had not been seen for several days after a boyfriend of one of the occupants expressed concern, police said.
