As dawn approached yesterday, a team of Frederick County Sheriff's Department investigators completed a task that had taken them all night -- unearthing two decomposed bodies in shallow graves in a field.
By yesterday afternoon, Frederick County Sheriff Carl R. Harbaugh got the word from the state medical examiner's officer.
The bodies were those of Hans and Ruth Koenig, an elderly Clarksburg couple who had been reported missing Thursday. The couple were identified through dental records.
Sheriff Harbaugh said the Koenigs were last seen June 20 and were reported missing 10 days later. An autopsy showed Mr. Koenig, 76, and Mrs. Koenig, 64, had each been fatally shot.
By yesterday evening, the county Sheriff's Department had obtained a warrant charging the couple's son, Bruce Wayne Koenig, 45, in the deaths of his parents.
Authorities could not locate Mr. Koenig yesterday and issued a multistate alert for him.
They said he may be traveling to San Antonio, where he has lived in the past, in his parents' beige 1985 Cadillac Eldorado with Maryland tags PXA 963.
Police described Mr. Koenig as 5 feet 9 inches tall, weighing 210 pounds, with reddish-brown hair and blue eyes. He is deaf in his right ear.
Anyone with information is asked to call the county sheriff's office at 301-694-1046.
Sheriff Harbaugh said the Koenigs, both retired, lived in a quiet section of Clarksville, in the southern tip of the county. He described their neighborhood as quiet and relatively crime-free.
The Koenigs' bodies were discovered several miles to the north, just off Reich's Ford Road, east of the Monocacy River, Sheriff Harbaugh said.
"We really haven't determined a motive at this time," the sheriff said. "There's all sorts of speculations at this time, but we really don't know."
After the Koenigs were reported missing by family and friends on Thursday, Sheriff's Department investigators began searching for them. Ultimately, their search led them to a patch of land southeast of Frederick.
Sheriff Harbaugh said investigators learned that Bruce Koenig had been negotiating to purchase the rural property.
Saturday night, investigators brought Tfc. Chuck Creswell and his search dog to the scene.
Before long, the dog had reacted to a patch of ground. The investigators obtained a search warrant and began digging, being careful not to disturb evidence.
Sheriff Harbaugh said it took from 9 p.m. until 4:30 a.m. to finish the task.
The sheriff said that a house is located on the property where the bodies were found, but that the house is vacant.
The bodies were discovered nearly 100 yards from the house, he said.
