Tracy Roberson was released from jail shortly after 6 p.m. Thursday after a judge approved her request for a $25,000 appeal bond, a Tarrant County spokesman said.
Tracy Roberson was sentenced to five years in prison on Monday for her role in the December 2006 shooting death of her lover, Devin LaSalle, 32.
Roberson found LaSalle and his wife embracing in a truck in front of the Robersons' south Arlington home.
After Tracy falsely cried out that she was being raped, Darrell Roberson fatally shot LaSalle, police said.
A grand jury declined to indict Darrell Roberson.
Jurors convicted Tracy Roberson of involuntary manslaughter, believing the prosecution's assertions that her actions led to LaSalle's death.
