Authorities said Blevins lost control of the 2005 Toyota Corolla and crashed into a tree on the side of Wilkerson Road.

The two rear seat passengers, 17-year-old David Waag and 15-year-old Connor Williams, died as a result of their injuries. Blevins and the front seat passenger, 17-year-old Zacharia Knauer, were treated for their injuries at Soin Medical Center.

Waag was a senior and played soccer at Greenon High School. Williams was a sophomore at Global Impact STEM Academy and played football for Greenon.

Blevins had more than three times the state’s legal limit for cannibinoids, the active components of marijuana, in his blood system, according to Lt. Matt Schmenk, commander of the Ohio State Highway Patrol Xenia Post.

The state’s legal limit for marijuana in the blood is set at 5 nanograms per milliliter. Blood test results indicate that Blevins had 17.8 nanograms per milliliter of cannibinoids in his blood system at the time of the crash, Schmenk said.

If the results are from a urine test, the state’s legal limit is set at 15 nanograms per milliliter, according to the patrol.

Schmenk said he was not personally at the scene and cannot affirm if there were signs of intoxication on the driver, but the investigating officer, Trooper Brandon Williams, will testify as to whether there were signs of the driver being intoxicated at the scene.

“The officer who spoke with him, they have to see those physical signs of impairment,” he said. “There are different levels of impairment and there are different tolerance levels. (Blevins) deserves to have a fair case and the officer will testify as to what he saw.”

Blevins was arrested over the weekend at his home by the Clark County Sheriff’s Office. He was booked into the Greene County Jail and subsequently posted 10 percent of the $50,000 bond set by Judge Stephen Wolaver of the Greene County Common Pleas Court.

Blevins’ attorney, Jon Paul Rion, said his office is just starting their investigation to determine if anyone in the vehicle was “actually under the influence of anything.”

“The mere presence of marijuana in the system is not relevant in and of itself as to whether or not the car was operated properly,” said Rion, noting that marijuana can remain in a person’s body for 30 days.
