Anne Arundel County police are investigating two separate incidents that left four county residents dead -- a married couple shot Tuesday night in an apparent murder-suicide, and a mother and son in Severn who were found dead that afternoon in a case in which police have not ruled out accidental causes.
Police said that about 11 p.m. Tuesday, Scott Christopher Naumann, 40, fatally shot his wife, Lenette Ann Naumann, 36, at their home on Elm Road in Millersville. He then turned the handgun on himself.
A juvenile relative was inside the house at the time and told detectives that the couple had argued shortly before the shootings.
Neighbors of the Naumanns said yesterday morning that they hardly knew the couple, who had moved to the block last spring.
Police spokesman Sgt. Shawn Urbas said officers responded to the home on Halloween for what is known as a "domestic standby" -- typically a request for an officer's presence while someone returns to a residence in a tense situation to gather essential personal items.
Police records did not indicate who called for assistance in that instance, Urban said. According to court records, Scott Naumann had a history of legal troubles, both criminal and civil.
He was charged with battery in 1989 and was sentenced to probation before judgment.
Last summer, Naumann was granted physical custody of his teenage daughter after becoming embroiled in a dispute with his ex-wife.
The Naumanns' deaths came days after Carolyn and Robert Dixon of Glen Burnie were found fatally shot inside their home Saturday night. The married couple had a recent history of domestic violence.
In the case of the two people discovered dead at their home in Severn, police said yesterday that foul play is not readily apparent and that they are continuing to investigate.
Authorities were called to the home in the 600 block of Queenstown Road on Tuesday to check a report of a woman lying in the side yard. Urbas said the woman, Emma Snyder, 87, was found by a utility worker about 1 p.m. near the meter that he had intended to read.
Snyder's son, Richard Snyder, 56, was found dead inside the house, Urbas said.
Information was not available yesterday on how long the two had been dead. Their Severn home -- a dilapidated farmhouse surrounded by junked cars, old tires and scrap heaps -- is at the end of a winding driveway and is barely visible from the road.
Urbas said the Snyders' bodies had no signs of trauma, and investigators are not ruling out any causes, including the possibility that the two were killed by carbon monoxide gas in their house. The home was cold, its heat was either turned off or malfunctioning, when officers arrived, he said.
