SALT LAKE CITY — A popular longtime TV news anchor was arrested Wednesday for investigation of drunken driving.

KUTV 2 News anchor Shauna Lake Marshall was booked into the Salt Lake County Jail for investigation of DUI, having an open container in a vehicle on a highway, using plates registered to another car and failing to register or driving with an expired registration.

Lake was reached by phone Wednesday but did not comment about the arrest. No charges had been filed as of Wednesday evening.

A Utah Highway Patrol trooper noticed a white Land Rover was traveling under the speed limit on I-215 in the far left lane about 12:18 a.m. Wednesday, according to a Salt Lake County Jail report.

The vehicle was moving east near 1200 East and after making a traffic stop, the trooper could smell "the strong odor of an alcoholic beverage coming from inside the vehicle," the report states. No passengers were inside.

The driver had "red, bloodshot eyes," the trooper wrote, and a clear plastic cup with a straw sticking out was visible on the center console of the vehicle. Lake said the cup was empty and handed it to the trooper.

"I smelled the liquid which was in the cup and it smelled like an alcoholic beverage," the report states.

Lake said she had taken two sips of an alcoholic drink prior to driving and later said the clear cup contained beer, which she had split with another person, according to the report.

The trooper conducted field sobriety tests. "During the Nine Step Walk and Turn, (Lake) left the starting position, stepped off the line, missed heel to toe, made an improper turn and started the test too early," the trooper wrote. She also allegedly swayed while standing on one leg.

Reached late Wednesday, KUTV news director Mike Garber said the station does not comment on personnel issues. He also declined to comment on Lake's employment status.

Lake was not on the air Wednesday.

According to the report, the trooper told Lake she was pulled over because the license plate was returned "canceled" and was registered to a black Land Rover, not a white one.

Lake first joined KUTV in 1994 as an anchor for the station's morning news show. She began her broadcasting career at BYU and is the mother of two sons, according to the station's website.
