Fatal DUI wreck plea gets Lawton man 25 years to serve

A Lawton man will serve 25 years in prison after pleading guilty to killing a Missouri man in a September 2022 drunk-driving wreck.

On Wednesday, Shaun Michael Beatty, 36, pleaded guilty in Comanche County District Court to a felony charge of second-degree murder, as well as misdemeanor counts of driving without a valid license, failure to maintain insurance and failure to have an updated tag, records indicate.

Presiding District Judge Emmit Tayloe sentenced Beatty to 40 years with 25 to serve and 15 suspended for the felony charge, records indicate. Due to the nature of the crime he will have to serve 85 percent, 21 years and three months, before consideration for parole.

Beatty also will have to register under the Mary Rippy Violent Offender Act and will have to pay just under $3,000 for fines and court costs as well as $16,714.76 in restitution.

Beatty crashed his Ford F-350 pickup into a motorcycle driven by Robbie Mizner, 62, of Belton, Mo., on Sept. 20, 2022.

Mizner was driving his Harley-Davidson motorcycle southbound on Oklahoma 58 shortly before 4 p.m. when a northbound Ford F-350 pickup traveling left of center driven by Beatty attempted a left-hand turn at Meers/Porter Hill Road, according to the Oklahoma Highway Patrol. The motorcycle collided into the front end of the pickup, pinning Mizner into the grill. He was freed by Medicine Park firefighters using the Hurst Tool.

Trooper Zachary Johnson stated Beatty smelled of alcohol at the scene, according to the probable cause affidavit.

A blood draw was taken after Beatty was medically cleared; he was treated for minor injuries at the scene. Beatty failed the field sobriety test and a portable breath test showed alcohol was present in his system, the affidavit states.

Beatty has a prior driving under the influence conviction from 2019 in North Dakota, the affidavit states. It was learned his driver’s license was suspended by the Colorado Department of Public Safety. His truck had no insurance and expired tags as well, Johnson stated.
