SHAWNEE, Kan. — A Shawnee teenager is now facing charges in a deadly crash that left a 71-year-old man dead over the weekend.

The 17-year-old, who FOX4 is not naming unless he’s prosecuted as an adult, has been charged with one count of involuntary manslaughter, one count of aggravated battery causing great harm, and one count of a juvenile in possession of a firearm.

The Johnson County District Attorney’s Office has already filed a motion to charge the teen as an adult.

The deadly crash happened around 4:30 p.m. Sunday near Blackfish Parkway and Lackman Road in Shawnee.

According to a Shawnee police report, the teenager told police he thought he could beat the light and was speeding before the crash.

He crashed into a car stopped at the intersection, pushing it into another vehicle in front of it, the police report says. All three vehicles ended up in the middle of the intersection.

Leland R. Scott, a 71-year-old from Shawnee, was in the first car that was hit and died from his injuries. A 69-year-old female passenger in his vehicle was hospitalized with critical injuries. No one was injured in the other car that was hit.

The police report indicates the teen had consumed alcohol and used illegal drugs.

The report says the teen took a breath test and had a blood alcohol level of 0.176 — two times over the legal limit for adults 21 and older to drive. However, at this time the 17-year-old is not facing any charges related to drunk driving.

Witnesses to the crash said they did everything the could to save the 71-year-old’s life.

“We just went car to car to find out who was the sickest,” Dr. Stefanie Ellison said.

She usually works in the emergency room, but Sunday afternoon Ellison was on the corner of Blackfish and Lackman. She and her husband, a surgeon, were behind the crash and ran to help. 

They met a firefighter, paramedic and nurse practitioner — all trying to keep their neighbors alive before emergency responders got there. 

“Everyone talking, helping, guiding, you know exchanging out to do CPR,” Ellison said.

“His best option to survive was because of the people who were there. It’s just unfortunate his injuries were so severe.,” Ellison said.

“Every day that I provide care, it’s very inter-professional between all of us, trying to do the right thing, and that’s what I saw right then and there on the corner of Blackfish and Lackman.

“It was just really tremendous, the humanity and how many people stepped up to the challenge and did the best that we could it a tough situation.”

Ellison sends prayers and support to the Scott family. She also hopes to connect with the team who tried to save his life. 

“It would be nice to get together with those people in Shawnee that stepped up to talk about it and grieve,” Ellison said.
