A Shawnee man has been charged with a felony count of first-degree manslaughter in connection with a 2017 traffic accident that killed a motorcycle passenger.

Court records show Charles David Lawrence, 36, was formally charged Wednesday in Pottawatomie County District Court.

He is accused, on our about July 26, 2017, of unlawfully, but without a premeditated design to effect death, of causing the death of Shelly Jane Stewart while engaged in the misdemeanor of driving a 2008 Yamaha motorcycle while under the influence of an intoxicating substance, court documents allege.

While driving the motorcycle, the filing alleges the defendant crashed the motorcycle and his passenger died from injuries suffered in that crash.

The Oklahoma Highway Patrol said that accident occurred about 3:14 a.m. on the Interstate 40 eastbound on-ramp from U.S. 177 northbound.

After that crash, troopers reported a 2008 Yamaha motorcycle driven by Lawrence was traveling eastbound on the I-40 on ramp when he lost control, causing the cycle to overturn one-fourth time onto its left side. He and his passenger, Stewart, 43, of Shawnee, were ejected from the motorcycle, the OHP reported.

Both were transported to unspecified hospitals and Lawrence was admitted in fair condition for treatment of head, internal and external trunk injuries, while Stewart was admitted in critical condition with head and internal trunk injuries.

She died on Aug. 5, 2017, according to obituary information.

Cause of the collision was listed by OHP as going too fast to negotiate a curve in the roadway; helmets were not in use.

According to the court filing, a warrant also was issued in the case. If convicted, the defendant could face imprisonment for no less than four years, the filing shows.
