A Eugene man is under investigation after Eugene police said he was suspected of driving under the influence of alcohol, marijuana, methamphetamine, and possibly Molly and cocaine.

According to a search warrant affidavit filed in Lane County Circuit Court this week, Christopher Emerson Hart, 32, was reported to police by his ex-girlfriend, who said Hart had shown up at her work the morning of Sept. 26 and forced her to hug him after sending a series of threatening text and voice messages, which she showed police. She told police he was high on meth and gave the officer his address, the affidavit states. The officer wrote in the affidavit that he had probable cause to arrest Hart for telephonic harassment and physical harassment.

A Eugene police officer went to Hart's home and witnessed him drive up to the address and park in the middle of the cul-de-sac, "not in a legal parking space," the affidavit states. Hart got out of the car just as the officer got out of his patrol vehicle, and he told the officer he was texting his girlfriend and had a breakup, according to the affidavit.

The officer, standing three feet from Hart, wrote he could smell alcohol and marijuana on Hart's breath.

Hart was allegedly sweating profusely, speaking rapidly and unable to control his body twitching, the affidavit states. He refused to speak to the officer without the presence of a lawyer, and was arrested. He refused to undergo field sobriety tests or take a breathalyzer test, the affidavit states.

Hart had two plastic bags on him at the time of his arrest, the affidavit states — Hart allegedly told police the bags contained Molly and cocaine. The officer believed the Molly may have actually been meth, the affidavit states. The search warrant sought to collect two vials of blood from Hart. It was granted and executed on Sept. 27.

Hart was cited for refusing to take a test for intoxicants, driving with a suspended or revoked license, and driving without privileges. While Hart was arrested on suspicion of harassment, telephonic harassment, unlawful possession of methamphetamine, unlawful delivery of marijuana, unlawful possession of cocaine, and DUII, formal charges have not yet been filed as the investigation is ongoing.
