Ollin (Renee) Crawford, a 26-year-old Laurel woman convicted in the five so-called "grenade lady" robberies in Fairfax County last fall, was sentenced yesterday to 70 years in prison.

Fairfax Circuit Court Judge J. Howe Brown said he imposed the maximum sentence set by the jury because the evidence against Crawford in the five crimes was "overwhelming."

Crawford, who steadfastly maintained her innocence, will be eligible for parole in 11 1/2 years. Her attorney, Barbara Kimble, said she will appeal.

During a three-day trial in January, 11 witnesses identified the then-pregnant Crawford as the bandit who coolly walked into five Fairfax banks during a three-month period and, claiming to have a hand grenade in a sock, demanded money.

More than $10,000 was taken in four successful robberies, none of which has been recovered.

Crawford was convicted on four charges of robbery and one of attempted robbery.

In contrast to her calm and expressionless demeanor during her trial, Crawford cried several times at yesterday's hearing.

As she was led from the courtroom she began sobbing uncontrollably, crying, "Oh Mama! Mama, I love you!"

She gave birth earlier this month to her third child, a boy, while under guard in Fairfax Hospital.

Crawford faces another bank robbery charge for a similar incident in Montgomery County in September.
