(Vancouver, WA) -- A missed text message delayed police response to a murder-suicide in Vancouver that left five people dead. The Clark County Sheriff's Office says the suspected shooter was an adult male. The victims appear to be the suspect's wife, two adult daughters, and the suspect's adult brother. The Sheriff's Office was asked to do a welfare check, because of a text message where a family member said they had harmed people at the house. The text came in four hours earlier, but wasn't discovered until around 1 o'clock Sunday afternoon. When deputies arrived, all five people were dead from apparent gunshot wounds.
