A former Washington woman will spend at least three years in prison after pleading guilty in connection with the death of a St. Louis County man on an Arkansas highway.

Alexandra Adams, 24, pleaded guilty in an Arkansas court earlier this week to charges of negligent homicide, first-degree battery and driving while intoxicated, according to published reports.

Adams received an 18-year-prison sentence and will have to serve three years before being eligible for parole because she was charged as a persistent offender.

The woman was living in a Washington apartment March 7, 2010, when she wrecked a car on Pottery Road at Holtgrewe Road. Three other people were in the car at the time.

Adams later pleaded guilty to three counts of second-degree assault and was given three five-year suspended sentences, given 120 days’ shock time in the Missouri Department of Corrections and ordered to undergo an alcohol/drug treatment program.

After her release, she was placed on five years’ supervised probation.

On Feb. 28, 2014, Adams was driving an SUV on an Arkansas interstate in a construction zone when she lost control and crashed. Arkansas authorities later said she had a blood alcohol content of 0.24 percent — three times the legal limit.

David P. Moessner, 51, of Wildwood, was struck by another vehicle and killed when he went to assist Adams and a passenger in her car.

Police said they smelled intoxicants coming from the vehicle Adams had been driving and saw a box of Budweiser beer bottles in the back of the vehicle, according to court documents. A couple of the bottles were open, the affidavit states.

Under the plea bargain, Adams must abide by a suspended sentence agreement for 10 years after her release from prison. She received 221 days of jail credit for the time she spent in the Benton County Jail awaiting trial. Adams must pay $1,750 in court costs.
