Ollin Crawford, the 26-year-old Laurel woman who was charged Tuesday by Fairfax County police with one of the six "grenade lady" bank robberies, was charged yesterday with another of the robberies.

She was arraigned in Fairfax County General District Court yesterday morning on the earlier charge of robbing the First American Bank at 6565 Little River Turnpike Aug. 27. Her bond was set at $25,000.

Later in the day, she was charged with the first of the six robberies, of the Sovran Bank, at 7220 Columbia Pike in Annandale on Aug. 23. Bond was set at $25,000 for that charge as well.

Kenneth E. Labowitz, Crawford's attorney, said yesterday his client denies any involvement in any of the series of similar incidents in the Washington area in which a slim woman dressed in gray has on six occasions entered a bank, claimed to have a hand grenade, and demanded money.

"That's what she says -- that she has nothing to do with this," Labowitz said after the arraignment. He said that as far as he knew, police have no physical evidence tying Crawford to the robberies.

Crawford permitted police to search her home, and police have said they seized some items of clothing similar to that worn by the woman robbing the banks.

Labowitz said the only item police took from Crawford's home was a gray skirt. "My wife has a gray skirt in her closet, and I would bet that the majority of people in the Washington area have a gray skirt in their closet." The woman who committed the robberies was described by police as wearing pants.

Fairfax police said yesterday Crawford had not been a member of the Army Military Police unit at Fort Belvoir, as they reported on Thursday, and would not have had access to hand grenades, as they also reported.

Crawford was a clerk typist in the military police office at the Army post in Fairfax, her attorney said.
