Officers located Greer at the scene and noted the smell of alcohol. Field sobriety testing was conducted, and Greer’s preliminary breath test measured .086. Greer admitted to officers that he had been driving in excess of the speed limit and was looking down to adjust his climate control when the collision occurred.
A blood draw taken within two hours of the crash showed Greer’s ethyl alcohol concentration at .057. Toxicology reports also revealed the presence of delta-9-THC, hydroxy-THC, carboxy-THC, cocaine, cocaethylene and benzoylecgonine, a metabolite of cocaine, in his system. Additional reports are pending, according to court documents.
The complaint states that, given the risk Greer poses to public safety, a warrant was requested for his arrest. Greer is currently in custody at the Hennepin County Jail.
The charges were filed Thursday, June 25. A court date has not yet been set.
