Arlen Fleenor shared his home in Richland with Robert King and Cynthia Bynum for more than a year.
"I have known the family since the kids were born, they called me grandpa," said Arlen Fleenor.
He tells me they were on their way to a job interview in Moses Lake when this happened Wednesday morning on I-182. State troopers say Robert and Cynthia were in a heated argument when their car flew off the interstate. Cynthia went through the windshield and died at the scene. Robert was taken to Kadlec where he was released later that day. Neighbors were stunned.
"Just can't take anything for granted, everyday it's just those little things you don't expect to happen, they can change our lives," said next door neighbor Melanie Cushing.
Troopers also say drugs or alcohol could be involved, but, Arlen says he doesn't believe that.
"This is my house, no drugs in there," said Fleenor.
The Bynum family decided not to comment on the accident. Neighbors say the couple was like any other.
"Very family oriented, seeing them outside a lot together, sitting in the backyard, playing with the kids, sitting on the porch, talking, planting flowers together," said Cushing.
"They were just a regular family," said Fleenor.
Now, it's a family looking for answers.
"One of them is missing and it's really a shock, to see someone you know, is pretty hard," said Fleenor.
Troopers tell KEPR it will take 6 weeks until they can confirm if any drugs or alcohol were involved. They also tell us that Cynthia Bynum was not wearing a seatbelt at the time
