VANCOUVER, Wash. -- An incomplete 911 call from east Clark County Monday morning led to discovery of a double homicide, involving a mother and son from Vancouver.

The two victims were identified as Evelyn Wastler, 86, and her son, Donald Wastler, 58.

Emergency dispatchers received a 911 call just before 5 a.m. from a residence on NE 212th Avenue but no one spoke on the phone.

Deputies went out to do a welfare check and discovered a dead man inside with an apparent gunshot wound.

As police searched the house they also found a dead woman in a bedroom, who also had been shot.

Investigators could not immediately determine the nature of their deaths, except to confirm the gunshot wounds, but said there were not currently any outstanding suspects.

A medical examiner will conduct autopsies on the two bodies Tuesday.

Clark County investigators are on the scene.
