NORTH BEND, Ore. -- There are still many unanswered questions about how 30-year-old Oen Nicholson made his way from a wrecked car in Noti to the police department in Milwaukee, Wisconsin, about 2,200 miles away.
Here's what we know so far.
At about 10 a.m. on June 18, Nicholson hit an elderly couple with a car at the RV campground near Mill Casino in North Bend. Anthony Oyster, 74, was killed and Linda Oyster, 73, was seriously injured.
Minutes later, North Bend police were called to Herbal Choices Marijuana Dispensary where they found the body of 47-year-old Jennifer Davidson. Nicholson reportedly shot and killed her, according to police.
Shortly after, police found the body of Nicholson's father, 83-year-old Charles Nicholson, at the RV campground near Mill Casino. The suspect reportedly sliced his father's throat. The exact time this murder happened is still unclear.
Nicholson fled the scene in his father's pickup truck, police said.
At 12:10 p.m., the Lane County Sheriff's Office received reports of a single-vehicle crash on Highway 126 near Noti.
Then, at 12:19 p.m., the first Lane County Sheriff's Office deputy arrived on the scene, but the driver was nowhere to be found. Officials quickly determined the vehicle involved was linked to the three earlier murders that occurred in North Bend.
A witness reported seeing the driver run into the woods, and several law enforcement agencies began working to close down Highway 126.
"The person had last been seen going off into the woods," Lane County Sheriff's Office spokesperson Sgt. Tom Speldrich said. "It didn't take long at all for us to realize that the vehicle that had been crashed or driven off the road was the suspect's white dodge pickup truck earlier from Coos County."
Meanwhile, at 12:30 p.m, 34-year-old Laura Johnson was preparing for her lunch break at Cabela's on Gateway Street in Springfield.
She was seen walking to her car and leaving for her break. Security footage showed Johnson later returned to her original parking spot. This is when police said she was approached by Nicholson. She was reported missing the next morning.
Back in Noti, authorities locked down Highway 126 by 12:45 p.m. at the latest, according to the sheriff's office. Highway 126 remained closed until 5:20 p.m., officials said. That's when authorities determined the suspect had likely already fled the area.
Sunday morning at 6:05 a.m., Nicholson turned himself in to authorities in Milwaukee, Wisconsin. Johnson was also found in Wisconsin, according to the Springfield Police Department. She flew back to Oregon and was reunited with her family that same night.
