A 37-year-old Redmond man was taken to Evergreen Hospital and his 4-year-old son was transported to Seattle Children's Hospital for a suspected heroin overdose.
Redmond police and fire were called to the residence in the 14100 block of Northeast 72nd Street just before noon. A woman called 911 after finding her husband and child breathing but unconscious.
Based on drug paraphernalia at the scene, police suspect that the father and son had been injected with heroin.
Police have responded to calls at the residence in the past, but those calls didn't necessarily involve people involved in today's incident.
A spokesman for the Redmond Police said the father are son are both listed as stable and sedated.
The incident is still under investigation, but Redmond police said they don't believe anyone else was involved.
