Federal prosecutors are recommending a prison sentence of four years and nine months for a Virginia woman who lied to investigators about supporting the Islamic State militant group.

That's eleven months more than defense attorneys are suggesting. Heather Elizabeth Coffman will be sentenced May 11 in Richmond.

Coffman posted numerous messages on Facebook supporting the Islamic State and tried to help a man make arrangements to train and fight with the group in Syria. She also tried to make similar arrangements for an undercover FBI agent.

Coffman's attorneys describe her as a gullible loner who didn't fully understand the gravity of her actions. Prosecutors said in court papers filed late Monday that Coffman was a serious jihadist who was headed down a potentially violent path before she was caught.
