Baltimore police concluded yesterday that the fatal shooting of a Belair Road gun-store owner and the wounding of a bystander were the work of eight people, not five.
Four suspects have been taken into custody, and warrants have been issued for three others, police said.
An eighth suspect has not yet been identified.
Three people were questioned and released.
The shootings occurred just before noon Wednesday when four men -- at least two of them armed -- entered the Northeast Gun Shop in the 4900 block of Belair Road.
Police said the owner, Charles E. "Eddie" Scheuerman, 53, was shot in the chest with a shotgun before he could say anything and died a short time later at the Francis Scott Key Medical Center.
An electronics salesman, Michael Berman, 42, who lives in the 11700 block of Morning Mist Lane in Columbia, was then shot in the upper back by a second gunman. He was reported in stable condition last night at Johns Hopkins Hospital.
L The robbers emptied gun cases on two walls before they fled.
Dennis S. Hill, a police spokesman, said 35 of the 43 weapons stolen from the gun shop were still unaccounted for.
Weapons recovered from a house included four .45-caliber handguns, three .357-caliber handguns, one 9mm handgun and a sawed-off .30-30-caliber rifle that the men had before the shootings, Mr. Hill said.
Detectives believe that the suspects disposed of the remaining weapons before three of them were arrested on Clendenin Street within an hour of the robbery and shootings.
Those arrested were identified by police as Rodney Demon Brown, 23, of the 1200 block of Clendenin Street, Malcolm Michael Bradford, 21, of the 2300 block of Brookfield Avenue, and his half-brother, Keith Bradford, also 21, of the 2900 block of Pendoll Road.
A fourth man, Ulysses Grant Scott, 22, of the 1800 block of Thomas Avenue, was arrested in the 2300 block of Brookfield Avenue.
All have been charged with first-degree murder, attempted murder, robbery with a deadly weapon and two handgun charges, Mr. Hill said.
He said warrants have been issued for Kevin Terrell Brown, 18, of the 5900 block of Radecke Avenue, Charles Ray Randolph Jr., 22, of the 500 block of Gold Street, and Lawrence Bell Jr., 38, of the 2300 block of Druid Hill Avenue.
Mr. Hill said it appears the suspects had plotted the robbery to get weapons they could sell.
"They were clearly after guns. No money was taken," the spokesman said. "That's a very salable commodity on the streets."
Detectives searched all three cars used in the robbery and several houses without finding any drugs or additional contraband. The cars were registered to suspects or relatives, police said.
Police said it does not appear that Wednesday's shooting was related to a robbery attempt Nov. 7, 1990, at the gun shop in which three men, one armed with a sawed-off shotgun, were arrested.
