Two separate explosions kill two in Grant County; Officials calling both suspicious

Updated:

MOSES LAKE, Wash. - Two people are dead after two separate explosions in Grant County. Those explosions are now under investigation by Grant County Sheriff deputies.  Deputies are also looking into a possible connection to a pipe bomb explosion two weeks ago that blew up a pick-up truck.

On Saturday August 2nd William Arleigh Walker, 69 of Moses Lake, was found face down in his shop by his grandson. Walker's grandson, 28-year old Andrew Otto of Moses Lake, told Sheriff deputies he had to move pieces of shop equipment to get to his grandfather in an attempt to help him.

Grant County Fire District 5, along with sheriff's deputies arrived at the scene and found William Walker had some how experienced severe trauma due to a possible explosion and had received wounds to his neck and chest.  Grant County officials pronounced Mr. Walker dead at the scene.

Detectives from the Sheriff's department and Washington State Patrol Crime Investigative Detective (CID), were called to the scene by Grant County Coroner Jerry Jasman. The scene was processed as a crime scene and evidence found at that scene was collected.

On Sunday, August 3rd at about 12:34 a.m. someone called emergency dispatch and told the dispatcher an explosion had occurred and a male was lying on the floor of his kitchen with a severe wound to his chest and stomach.

Grant County Fire District 5 and Sheriff's deputies arrived on scene to find Javier Martinez Adame, 53 a Moses Lake resident, dead.  According to deputies at the scene, the air in and around the house was pungent with the smell of sulfur.

It was determined that an explosive device Mr. Adame may have been handling at the time had exploded killing him almost instantly.  Deputies performed a search of the home for other victims or visitors and locked down the home.  An Explosive Ordinance Detection (EOD) team was sent from the Army's firing range in Yakima. 

When the EOD team arrived on the scene, they decided that because of damage to the property, plus the number of out buildings nearby, a bomb-sniffing dog would better perform the search for other explosives.

With the assistance of the bomb-sniffing dog, the Army's EOD team cleared the property where Adame was found and determined it to be safe.  The teams did find evidence that material used to make pipe bombs was present, including pipe, end caps, nails, electrical wires, and timing devices.  After this discovery, sheriff's deputies locked down the home and a search warrant for the residence was requested.

Grant County sheriff's investigators and WSP CID investigators determined it was suspicious that two explosives could go off, killing two people, within 10-hours of one another.

A request was made of the FBI to send a team of forensic evidence special agents, known as the Emergency Response Team (ERT), to assist in determining if there is a possible connection with the pipe bomb explosion from two weeks ago and the two over the weekend.

On Tuesday, August 5th at 9 a.m. autopsies will be performed on both Walker and Adame at the Forensics Institute located at Samaritan Hospital in Moses Lake.
