Amanda Heiman has been convicted of procuring alcohol for a minor in a case that led to a deadly traffic accident in 2012.
Eighteen-year-old Jacob Dickmeyer died in that accident and his friend, Colby Burke, was seriously injured.
Court papers describe what led up to the crash at 208th Street and West Dodge Road.
In an affidavit, both Dickmeyer and Burke were carded by Heiman, a server at Fire Barn Bar and Grill. The teens gave Heiman their actual Nebraska driver's license, which showed they were younger than 21.
At least two other employees told Heiman not to serve Dickmeyer alcohol, but she told co-workers she didn't want to tell the teens no.
Investigators said when Jacob Dickmeyer left the bar and got behind the wheel of Heiman's car, his blood alcohol level was more than twice the legal limit. Officials have said the teens drank the equivalent of ten beers and eight shots of liquor.
A jury returned the guilty verdict on Thursday afternoon. Sentencing is scheduled for April 22.
