Bail was revoked yesterday for five men charged with brazenly robbing 42 people at gunpoint in a remote area of the Loch Raven Reservoir when a prosecutor said that after they were arrested, the suspects discussed killing the victims.

While the suspects were detained at the Cockeysville station shortly after midnight Saturday, police heard one of them say, "As soon as we get out of here, we've got to kill all of them," Assistant State's Attorney Richard K. Scott told District Judge Norman R. Stone III yesterday.

"They're all dead," another suspect agreed, according to a statement Officer Tim McGlaughlin gave to prosecutors, which Scott read aloud in court.

Then another suspect, according to Scott, was overheard saying they should have raped the female victims and "shot all of them while they were in the water."

Omar A. Harris, 20, Pierce D. Williams, 18, George S. Morgan, 23, Antonio J. Washington, 23, and Raymond J. Hurst, 19, are each charged with four counts of armed robbery, four counts of first-degree assault and four counts of handgun violations in the robbery about 6 p.m. Friday in an area of the reservoir known as "the cliffs."

A sixth suspect, Candace M. Greever, 30, is charged with the same offenses.

Greever is being held at the Women's Detention Center. The men are being held at the county Detention Center. Both jails are in Towson.

McGlaughlin said in the statement that he could not be sure which defendant made which remarks.

After hearing the police statement, the judge asked the suspects, who sat handcuffed together in two rows of benches in the Towson District Court, whether they had anything to say. Each declined to comment before Stone revoked their bails, which had ranged from $250,000 to $750,000.

The prosecutor later said that the threats showed the men are too dangerous to be freed before trial. "I think when Judge Stone learned of the threats, he took them very seriously," Scott said.

According to a statement of charges from police, the suspects terrorized the victims by pointing guns at their heads and faces, punching them, forcing them to strip naked and walk into the chilly reservoir. They also fired at least two shots - one into the water and one into the air - before robbing them of jewelry, cell phones and hundreds of dollars. Most of the stolen property was recovered, police said.

They believe the suspects planned the robberies and specifically targeted the victims, many of whom are from Kenwood and Sparrows Point high schools.

The victims, who were swimming and picnicking, were robbed in a hilly region of the reservoir that is a 25-minute hike from the nearest road and is a popular gathering spot, according to police, prosecutors and those familiar with the area.

Police also said yesterday that more suspects could be charged. "We know that this group of individuals were targeted, but exactly how and why this group was targeted is still part of the investigation," said Cpl. Vickie Warehime, a county police spokeswoman.

In a separate hearing yesterday, the judge agreed to reduce bail for Greever from $250,000 to $100,000 after her lawyer argued that she was not involved in the robberies and not present when the threats were made.

Greever has no criminal record and has a steady job as a nurse, according to her lawyer.

"She was in a bathing suit at the time of the robberies, and she was there swimming that day," Leslie J. Dobres, Greever's lawyer, told Stone.

Charles E. Greever, Candace Greever's father, said after the bail hearing that his daughter told him that she knew only one of the suspects, Harris, who is an ex-boyfriend. "Her problem is that she's got lousy taste in boyfriends," Greever said.

But according to the statement of charges, victims identified Candace Greever as having assisted the other suspects by yelling instructions to them, "making sure they checked the victims bags" for cell phones and other valuables.

Greever gave police several inconsistent statements but said she took three men in her 2001 Suzuki Vita to a gas station and met someone in another car before they drove in two cars to the reservoir, according to the statement.

Harris held a number of victims at gunpoint from a distance while Williams and Washington went up to groups of people and demanded that they strip naked and surrender their cash and valuables, according to the statement.

They hit one victim in the jaw and pointed a gun at him, and when the victim questioned whether the gun was real, one of the suspects fired the gun into the water before ordering the victim into the water, the statement said.

Williams, Washington and Harris were arrested after police saw them speeding east in a 1989 Chevy Cavalier on Loch Raven Drive. Greever and Morgan were arrested at the scene after victims identified them as suspects, police said.

Hurst admitted acting as a lookout when he was arrested about four hours after the robberies at the Wendy's restaurant on North Point Boulevard in Dundalk, police said.
