The Ohio woman who was inspired by an online group known as the “True Crime Community” to plot the bombing of a pipeline and another terrorist attack at a local bar was sentenced to 15 years in prison on Wednesday, authorities said.

Elizabeth Lecron, 24, was also sentenced to a lifetime of supervision for plotting the attack at a Toledo bar and an interstate pipeline in Georgia in 2018, the FBI said.

Lecron, along with her boyfriend Vincent Armstrong, became obsessed with mass shootings and other violent acts through the internet fetish group, authorities alleged after her arrest.

Lecron wrote letters to Dylann Roof and the pair visited areas associated with the Columbine high school massacre, the FBI said.

They also bought guns and went to the shooting range to practice ahead of their planned attack, which they called “D-Day.”

“D-day will be my salvation,” Lecron wrote as they were practicing for the shooting.

In addition to their gun arsenal, Lecron also bought two pounds of black powder and hundreds of screws to use in the pipeline bombing in Georgia.

“Today’s sentence reflects the severity of her conduct and is a recognition of the continued efforts by law enforcement to protect the public from all violent threats,” US Attorney Justin Herdman said in a statement after the sentencing.
