HINCKLEY, MN. (KBJR) - The 21-year-old woman who crashed into the 148th Fighter Wing Member on May 14th has been charged with criminal vehicular homicide.

According to court documents, Cambridge native, Tabitha Sue Sigler was under the influence when she crossed over the median and struck Master Sgt. David T. Greiner’s SUV while driving down I-35 South near Hinckley.

Greiner was pronounced dead at the scene.

The criminal complaint states that evidence of drug use was present in Sigler’s car.

Investigators found a scale with white residue that came back positive for methamphetamine after testing the substance.

Investigators reported finding a partially empty and recently opened bottle of whiskey and noticed a marijuana scent coming from Sigler’s car.

After airlifting Sigler to the hospital for life-threatening injuries, authorities obtained a search warrant to test her blood for substances.

Results came back positive for amphetamines, meth, and THC.

Back in January 2021, Sigler was convicted of a felony fifth-degree possession of a controlled substance in Hennepin County.

Greiner’s toxicology report showed no alcohol or controlled substances in his system, and was wearing his seatbelt at the time of the crash.

Greiner was a resident of Garfield, Minnesota. He served in the military for almost 20 years, and was set to retire in October.
