A local woman was arrested on charges of driving under the influence of drugs after she allegedly hit three parked cars and a Winterport business Sunday night.

Police say she made matters worse after she arrived at Waldo County Jail, when she apparently tried to alter the results of her drug test.

Laurie Uhrin, 41, of Winterport was initially arrested on an operating under the influence charge following a series of collisions that reportedly occurred just after 8 p.m. on Main Street in Winterport.

According to the accident report at the Waldo County Sheriff’s Office, Uhrin was headed north on Main Street in a 1997 Ford pickup when she drifted onto the right side of the travel lane and into a parked 1995 Ford pickup that was registered to 60-year-old Albert Hall of Winteport. Uhrin reportedly continued into the parking lot of Don Dickel Flooring, where she allegedly struck a parked 2008 Chevrolet cargo van. The report did not specify the registered owner of that vehicle.

The report stated Uhrin’s vehicle then struck the trailer hitch of a 2009 Chevy pickup that was registered to Dickel himself and continued into the stairs of the flooring business before coming to rest.

Waldo County Chief Deputy Jeff Trafton said neither Uhrin nor her passenger, 46-year-old David Pinkham, were hurt in the accident, and no one was hurt at the scene.

“It looks like it was all parked vehicles that were hit,” said Trafton.

Uhrin was arrested on the OUI charge, and Trafton said because Uhrin was charged with driving under the influence of drugs, she was required to undergo an examination with the county’s drug recognition expert.

Sgt. James Greeley, who serves in that capacity for WCSO, administered the test to Uhrin, which Trafton said included a urine test.

But when Uhrin handed over the cup containing the urine that was to be used in the testing, Trafton said, Greeley immediately noticed something unusual about the sample.

“Instead of urinating in the cup she just filled it up with water,” said Trafton.

As a result, Trafton said, Uhrin was additionally charged with falsifying physical evidence.
