A Silver Spring man charged in the slaying of his father was arrested yesterday after he led New Jersey police on a three-mile chase that ended when he dived into a swollen stream, authorities said.

Paul Christopher Ringe, 31, was being held last night in the Bordentown, N.J., jail on a first-degree murder warrant pending extradition to Prince George's County, authorities said.

Ringe's father, Fred Ringe Jr., 68, of the 10500 block of Proctor Street, was found shot to death shortly after midnight Monday in his law office in the 12800 block of Baltimore Avenue in Beltsville, police said. Fred Ringe's wife called police after he failed to return home from his office, police said. Fred Ringe's blue Volkswagen Beetle also was missing, police said.

Prince George's County police said they knew of no motive for the shooting.

Bordentown Township police said that an officer stopped Paul Ringe shortly after noon yesterday in the parking lot of the Sandman Motor Lodge Truck Stop near Route 206 and Old York Road off the New Jersey State Turnpike after noticing his "acting suspiciously."

When Officer Jeffrey Pippin asked Ringe for his identification, Ringe supplied his own and his father's and then began to run, Prince George's County and Bordentown police said.

Ringe ran into a thickly wooded area behind Bordentown Regional High School. More than 25 New Jersey state troopers and local officers searched for him with dogs and helicopters, Bordentown police said. Officers chased Ringe for more than three miles through rough terrain into a marshy area where Ringe dived into a 75-foot-wide creek, authorities said. Two New Jersey state police officers dived into the water and pulled him out, police said.
