While police haven't identified a suspect, authorities remain confident that the attack was targeted.

"Our clarification last night directly addressed comments made by Latah County Prosecutor Thompson, who said the suspect(s) specifically looked at this residence, and that one or more of the occupants were undoubtedly targeted. We remain consistent in our belief that this was indeed a targeted attack but have not concluded if the target was the residence or its occupants," a statement from the Moscow Police Department to WHD News on Thursday read.

Anyone with information about the incident is being asked to call Moscow police at 208-883-7054 or email tipline@ci.moscow.id.us.
