A District man has been arrested in the slaying of an armored car courier who was ambushed and shot outside a Hyattsville bank in August, Prince George's County police said yesterday.

A county police spokeswoman said Earl W. Davis, 34, was arrested in the 1800 block of Independence Avenue SW by U.S. Park Police shortly before 2:30 p.m. Monday. She said Park Police received information that Davis might be in the area and were looking for a gray Dodge pickup truck that he was believed to be driving.

Davis is one of two men suspected in the Aug. 6 killing of Jason Schwindler, 28, of Anne Arundel County. Schwindler was shot three times outside the front entrance of a BB&T bank branch, where he and another employee of the Dunbar armored car company had stopped for a delivery. The robbers escaped with an undisclosed amount of money.

Cpl. Diane Richardson, the police spokeswoman, said investigators searched a Jeep Cherokee that the suspects left at the bank after it was rammed by the armored car. She said that police found evidence that was subjected to DNA tests and that a "positive hit linked Davis to the homicide."

Last week, investigators obtained an arrest warrant for Davis, of the 200 block of V Street NE. He was charged with first-degree murder in the warrant. A second man, whose name was not released yesterday, is being sought by police.

Davis remained jailed without bond in the District last night and was awaiting a hearing on extradition to Maryland. No other details were made public yesterday about his arrest or about the evidence collected in the case.

"This was a terrible tragedy and our investigators worked very hard to close this case," Richardson said.
