Jurors took less than four hours to find Boswell, 26, guilty of first-degree murder, conspiracy to commit murder and improper disposal of human remains.
A three-judge panel will later decide if Boswell should be sentenced to death or to life in prison, the two options for someone convicted of first-degree murder. Boswell could become the first woman sentenced to death in Nebraska.
The Nebraska Attorney General's Office, which prosecuted the case, has said it will argue that the heinous nature of the crime warrants the death penalty.
Boswell, a former high school basketball and track standout from Leon, Iowa, does not have a history of assault crimes, which will likely be a mitigating factor against capital punishment.
Boswell's 53-year-old boyfriend, Aubrey Trail
was found guilty of first-degree murder a year ago. Jurors in his case took less than three hours to arrive at a verdict, a lightning-fast decision after hearing more nearly three weeks of sometimes grisly testimony.
His sentencing hearing is scheduled to begin in December.
