The time it takes from their apt. complex to Hogan Road, the Road listed on the court document, might take only 3 minutes, but it can take 5 minutes if you get caught at one of the 3 lights. Hwy 26 turns into Burnside Street. I am sure at most her work was only 3 minutes from her apartment.
If it is true that he pulled the gun on her at Hogan Street (aka 242nd St), then they would have to loop back around to get out to Dodge Park. When you go NW on Hwy 26/Burnside and you have to hang a right on Hogan Street, you can't turn left at that stop light. So the path I am assuming they took, would probably have to be North Hogan/242nd , right on Division, then either go straight on Division til you hit 302nd, right there, South to Lusted Road, then a Left on Lusted out to Dodge Park. That is about a 30 minute drive. But the court documents claim that the crime was committed on Thompson Road at South Roslyn Lake. Add another ten minutes up the windy road. Probably 40 minutes. The South end of Roslyn Lake has water I believe because of the natural springs and rain. The majority of the lake used to be filled up by the Little Sandy River and a water chute from Marmot Dam until they let the lake go dry a few years back. Now the North Road on the Lake is usually the busiest, because of fisherman and locals going to and from Sandy and the fishing spot at the Sandy Hatchery. I believe there is a Fire Station on that road. Now Thompson Road you have to actually go out of your way to go on the other side of the lake. Probably less traffic. If I remember correctly, when the lake was filled, there would be a line of fisherman up on the dirt wall in their chairs. When the lake got drained I am assuming all of the fish went as well, so there was only a small marsh left on the South end of the Lake where he threw his phone in and committed the crime.
Now the fact that he dumped evidence at Dodge Park baffled me, because of all of the fishermen there this time of year. It is prime Coho Season, with some Native Chinook and Summer Steelhead running. I was at Dodge Park a few days before this incident, on Sunday and the water was a bit murky but there were still a descent number of fishermen. About 10am the early fishermen are gone, then the after church or late bloomers head to the river, so you get a different crowd. Monday was a lot of rain, so that probably blew out the river and made it unfishable on Tuesday AM. But there are always the dedicated few on the river. Dodge park does have honeybucket bathrooms and I am not sure if they closed down the regular bathrooms. It would be tough to know if those cans were JH, or if they were left from someone else. I have had to jump over a lot of debris walking down to the river to fish. I am not sure where the LE found the evidence, but if it was toward the back of the park, I am sure that the fishermen didn't pay much attention, because you pull in the park and you are right at the river and parking lot. There is a road that takes you to the back, but I am not sure how they have that set up back there.
Now heading to Larch Mountain, I believe you can take Lusted Road West and a right on 302nd and that takes you to the back way without having to go through town, to the old Columbia Scenic Highway which in turn takes you to Larch Mountain area. So JH probably just used the 302nd Route , because it goes by farms and throws you out near Dabney Park.(Going North on 302nd turns into Kerslake Rd, before it hits Stark Street) I can not give you the timing on Dodge Park to Larch Mountain, because I have never been up there, but google maps might give you an idea. I am not sure if he gassed up before or after Larch Mountain. Either way the gas station is on top of the hill and he can turn around and go back down Stark Street toward Larch Mtn way.
As far as the Black Explorer. The first thing I noticed in the picture as well was the back tires muddy and the front ones pretty clean. That led me to believe that he had backed in to a muddy ledge or off road to hide the remains. Front tires on solid ground. As far as the license plate. I believe he ripped it off to hide the identity of the vehicle. I believe there might have been an Amber Alert that morning, Would have to be after CH called it in.
When JH parked the car at Walmart he knew the area, because he worked at Subway in the area up until last Summer. (Troutdale Outlet Mall) He probably walked up Wood Village Exit, through some trails near Mcmenammins (Halsey Street), threw the phone in the bushes and he was probably right at the bus stop near the apartments on 257th/Terrace Apts. 257th just happens to be a bus stop, near his old workplace. I am sure when he didn't have his bike he took the bus. I figured when they found the phone that it might be someone trying to return back to the apartment area via bus.
This is all speculation, but I thought I would throw my two cents in since it has affected our community so deeply. I did not know WH personally, but I had met her a few times at the drive thru and she was a very bright spirited warm lady. Our community is definitely shocked and saddened by her loss.
We are just armchair sleuths.
. Yawn!
