A 23-year-old man arrested last week after a stolen car eluding a police sobriety checkpoint landed in a Chevy Chase swimming pool was charged yesterday in the November 1984 slaying of Joseph Robert Drewer, a former member of the College Park City Council, Prince George's County police reported.

They said Lawrence Harold Morgan Jr. of 6904 Valley Park Rd., Capitol Heights, was arrested at the Montgomery County Detention Center and charged with first-degree murder. Police said a .38 caliber revolver had provided clues that led them to charge Morgan in Drewer's death.

Drewer, who was 38 at the time of his death, was on his way home from a state PTA meeting in Landover on the evening of Nov. 7, 1984, when he apparently picked up a hitchhiker on Riverdale Road.

Drewer's wife Happy reported him missing to police early the next morning. His body was found at 11 a.m. Nov. 8 in a woods in College Park.

He had been shot once in the chest and his Chevrolet van, and his wallet, credit cards and money were missing. Police located the van several days later in Seat Pleasant.

Morgan was arrested last Saturday by Montgomery County police on charges of car theft and possession of a handgun. Police said Morgan was a passenger in a car that sped from a routine sobriety checkpoint, leading police on a chase up Wisconsin Avenue that ended when the car crashed through a fenced yard and plunged into a swimming pool.

Morgan was pulled from the swimming pool while the driver of the car escaped. A handgun was also found in the car, but Prince George's police said another handgun led to their arrest of Morgan on the murder charge.

Morgan was taken before a Prince George's County District Court commissioner, who determined that he should be denied bond and returned to the Montgomery County jail.

Drewer was an accountant who worked out of his home and taught business courses at Prince George's Community College. He served one term on the College Park City Council, from 1979 to 1983. He was the father of three children.
