A Monday morning fire in Cedar Rapids has claimed a second person.

The Cedar Rapids Fire Department reports that Karen Louise Jacobs has died. The Johnson County Medical Examiner's Office informed the fire department of her passing late yesterday. Karen Jacobs was married to Ronald Jacobs, also 76, who was pronounced dead at the scene of the fire by the Linn County Medical Examiner. Karen Jacobs was taken to Mercy Medical Center in Cedar Rapids before being transferred to the University of Iowa Hospitals and Clinics.

The Cedar Rapids Fire Department responded to the call at 3701 16th Avenue Southwest, Lot 46, Monday morning at 7:34. They found both victims in the living room, where investigators determined the fire started on the couch. No official cause was determined due to extensive fire damage in the room, but smoking materials are believed to have been a contributing factor.

There were no working smoke alarms found in the home.
