An off-duty Waco police officer's blood alcohol content was almost twice the legal limit when he was arrested last week on a driving while intoxicated charge, an arrest affidavit states.

Patrick Joseph McKnight, 39, of Robinson, was arrested after he crashed his pickup through a barbed wire fence at about 3:30 p.m. Feb. 22 near Farm-to-Market Road 3400 and Estella Lane outside Robinson. McKnight, a nine-year veteran with the Waco Police Department, told Texas Department of Public Safety troopers who responded to the wreck that he had a blow out and lost control of his car, the affidavit states.

"However, the only tire that was off its rim was still intact. Mr. McKnight seemed to be unsteady on his feet, spoke with a slur and had the odor of an alcoholic beverage emitting from his person," the affidavit states. "Mr. McKnight stated that he had consumed a lot of alcohol the previous night. Mr. McKnight also stated he had consumed one beer during lunch."

The trooper had McKnight perform several field sobriety tests, and McKnight showed signs of intoxication, the affidavit states. McKnight submitted to a preliminary breath test for his blood alcohol content, which showed .148 percent. The legal limit is .08 percent.

McKnight did not consent to additional testing, but officials got a warrant to take a blood sample. Results of the blood test have not been released. McKnight was arrested on a misdemeanor charge of driving while intoxicated and released from McLennan County Jail after posting a $1,000 bond.

Waco police Sgt. W. Patrick Swanton said last week McKnight was placed on administrative leave immediately after the arrest, per police protocol. He will remain on leave pending the outcome of the case, Swanton said.
