"Somebody up there saw [the shooting], I'll bet you that," said the woman, who did not want to give her name for fear of reprisal. "There's those who see it and don't tell it, and there's those who live in it and don't tell it."

In Greektown, police asked Monday afternoon for the public's help in finding Chase, whom they dubbed the agency's top fugitive target.

Chase is the department's second "Public Enemy No. 1." The first, 25-year-old murder suspect Darryl Anderson, was captured last week by U.S. marshals in Alabama.

Maj. Bill Davis, standing on the soft rubber surface of a playground in the 4600 block of Gough St., told reporters that Chase had vaulted to the top spot because the killing of Ramon Rodriguez took place in a playground, a haven for children.

He said Chase, like Anderson, is believed to be a member of the Black Guerrilla Family gang. A photograph distributed by police showed that Chase, also like Anderson, has a tattoo of a cross between his eyes.

Court records show Chase was charged with armed robbery in late February, and on July 10 pleaded guilty to second-degree assault. He received a sentence of five years, with four years, four months and 15 days suspended.

Chase was released on July 11. Rodriguez, 21, was killed two nights later.

As the Greektown news conference concluded, police reported a shooting victim had walked into a West Baltimore hospital for treatment, then said that two men had been shot on the corner of North Milton Avenue and East Preston Street. A wide pool of blood stained the sidewalk, dripping off the curb and toward a storm drain.

Lt. Col. Dan Lioi said the younger victim, believed to be in his 20s, was shot in the head and critically wounded, while an older victim was shot in the arm and is expected to survive.

A blue bicycle lay on its side just inside the crime scene tape. It was not clear whether it belonged to a victim.

"We're not sure how the bike plays into it at this time," Lioi said.

Shortly after 11 p.m. Monday, two men were shot in separate incidents that were reported just minutes apart — one man shot in his right side at East 20th Street and Boone Street, another man shot in his arm and leg in the 2100 block of McCulloh Street, police said.
