The incident began shortly before 6 a.m. when three masked men broke into the home in the 7500 block of 44th Avenue NE while the two residents were asleep.
The robbers ordered both victims to the floor and tied them up, striking one in the head with a rifle butt, said Renee Witt of the Seattle police.
One of the masked men held both victims at gunpoint while the other two searched the home. Several valuables were taken, including the residents' vehicle.
After the suspects left the home both victims were able to free themselves and run to a nearby residence to call 911. The victims drove themselves to the hospital, where officers met with them, Witt said.
Additional officers responded to the residence along with robbery detectives.
Police at the scene said marijuana may have been involved, based on evidence in the house and statements from the victims.
The case remains under active investigation. Anyone with information is asked to call 911. Anonymous tips are welcome.
