'Blond Bandit' Stephanie Schwab Wanted By D.C.-Area Police In Carjackings

Baltimore County police are looking for help in locating an alleged carjacker and possible bank robber who has come to be known as the "Blond Bandit" in the D.C. area.

Twenty-six year-old Stephanie Lynn Schwab, a former member of the MS-13 gang, is thought to be responsible for a Nov. 19 carjacking at Virginia's Tysons Corner and an attempted carjacking Thanksgiving Day at a Shopper's Food Warehouse in Baltimore County.

Police also believe Schwab is also responsible for two recent Virginia bank robberies, one in Manassas and one in Springfield.

Schwab, who testified against former MS-13 gang members in 2005, is wanted by the Fairfax County Police and was a recent Prince William County Police Department's "Fugitive of the Week."

"We don't know what she's capable of, there could be additional crimes committed by this person," said Fairfax County police spokeswoman Lucy Caldwell, according to ABC7.

In related news, Patch reports that another carjacking was reported to Maryland police in Wheaton -- the fourth in the past week:

Montgomery County Police received a call at 1:02 a.m. from the Burger King at 12265 Veirs Mill Road, near the corner of Veirs Mill Road and Randolph Road.

Police say that the two victims, a male and a female, had driven to the Burger King looking for something to eat. They checked the restaurant door, but it was locked. Police say that two men sitting at a table outside the Burger King then approached the victims. One presented a handgun and told the victims to give him the keys to their car, a white Honda Civic. The suspects also demanded the victims' cell phones and a wallet. The suspects then took the vehicle and drove away.

Wheaton's three other recent carjackings are thought to be unrelated to the Burger King carjacking.

District of Columbia police, meanwhile, are still investigating 11 recent carjackings in the nation's capital.

WJLA has a roundup of area carjackings from the last few days. One from Northeast involves a 13 month-old baby, who, luckily, was quickly recovered.
