The bodies of the night supervisor of the White House mailroom and his wife were found in the living room of their home in Germantown yesterday after a newspaper delivery boy told police he saw a body through a window. Police called the deaths an apparent murder and suicide.

Montgomery County police said they believe that Benjamin Hailstorks, 45, shot his wife, Thelma Goins Hailstorks, 60, in the head with a handgun, then turned the weapon on himself. Mrs. Hailstorks' body was found lying on a couch and the body of her husband was on the floor next to her. A handgun was found nearby, police said.

The couple apparently had been dead for several days, according to police, who went to the home at 13075 Open Hearth Way when a newsboy reported that for the second day in a row he had seen what appeared to be a body through a window of the house.

Police gave no motive for the deaths and neighbors said they knew of no serious troubles involving the couple, whom they described as outgoing, friendly and cheerful.

A White House spokesman said that Hailstorks had worked there since 1958, with the exception of two years when he served in the military.
