An 18-year-old man confessed to fatally shooting another 18-year-old Thursday night at the first man's Dundalk townhouse, according to Baltimore County police, but told them it was an accident.
Police charged Tico Romain Thomas, 18, with first-degree murder in the death of David J. Arnold of Alexandria, Va.
According to the police report, officials received a call about a shot fired at the 200 block of Fleming Drive about 8 p.m.
When they arrived they discovered Arnold had been shot once in the stomach with a shotgun, police said. He was transported to Johns Hopkins Bayview Medical Center, where he was pronounced dead, police said.
At the home, Thomas told police "I shot him," according to the police report.
"Thomas waived his rights and stated that he did in fact shoot and kill David Arnold, however, it was by accident," according to the police report.
Neighbors said they heard noise coming from Thomas' home Thursday night, but did not believe it was fighting. They then heard one gunshot.
"I knew it was a gunshot," said Eliza Thomas, 42, who is not related to Tico Thomas and who has lived across the street for 30 years. "A woman I had never seen before ran out and said, 'Help me, help me.' "
Thomas was denied bail and is being held at the Baltimore County Detention Center.
Arnold's death is the county's 18th homicide this year. This time last year there were 16 homicides, police said.
