"Is it really that dark at 9:30?"
Yes. On July 22, the length of day was nearly 30 minutes shorter than it was a month earlier. The sky was clear last Friday evening around 9:30 p.m., so that would permit a bit more light in the sky.
"The father said it was 9:30 at night and he was only 30 feet away. Doing what?"
WTOL story :
"Scott Schultz was doing yard work ..."
Strong storms rumbled through the Toledo area on Friday afternoon, July 22, knocking out power in some areas and bringing down twigs to large branches. I can't speak for Oregon, but in West Toledo, last Friday's storm brought down a lot of tree debris, and the power was out for approximately four hours until around 6:20 p.m. Maybe the father was cleaning up storm debris in his yard, and he didn't want to wait until Saturday, and maybe he was too busy earlier on Friday evening to do the yard work in the daylight. The WTOL video shows trees around the home.
"I'm pretty sure that street has streetlights."
You can see streetlights in the WTOL video at the parent's home.
From the Jul 27, 2011 Blade story :
A woman, a complete stranger, was holding Scott Schultz’s 2-year-old son in her arms. She plucked the boy off of his motorized toy car at the end of his Eastmoreland Drive driveway and tried to put him in her car. Mr. Schultz, who was only about 30 feet away, ran for his son, Tyler, and was able to take him from the woman. A man, who was driving the car, got out and pointed a gun at the father.
From that description, it appears the father was in close proximity to both would-be abductors and the vehicle.
