District police can't find Matthew White or William Stewart.

They say White stabbed Daryl Canady to death in Southeast Washington in May.

They say Stewart broke into a woman's home in October, then fled after telling her, "I will be back. I'm going to get you!"

White and Stewart are two of the 30 fugitives to be named this month to the D.C. police department's lengthened list of most-wanted suspects.

The equation advanced by Police Chief Charles H. Ramsey last week amid a succession of high-profile shootings is this: Wanted List plus Publicity equals Safer Washington.

"If we can pick these people up, I think it goes a long way toward trying to stem the violence," Ramsey said. "It isn't the end-all cure, but it's a significant step forward."

The primary targets, Ramsey said, are the suspects "committing the violent crimes that are ripping our neighborhoods apart."

As a crime-fighting tactic, the expanded list is but one item on the flip chart. Ramsey announced last week that he intends to increase anti-gang efforts and--assuming the D.C. Council approves--hire more experienced officers from other departments.

Sentencing guidelines have been under discussion for two years, and a review of pretrial release procedures and the operation of the District's six halfway houses--four for men, two for women--is being undertaken by criminal justice system leaders.

A federal appeals court upheld the District's youth curfew law last month, making it more likely that the majority of D.C. youths under age 17 soon will be confined indoors after 11 p.m. on weeknights and after midnight on Fridays and Saturdays.

Curfew opponents, who expect to appeal the case to the U.S. Supreme Court, have asked the U.S. Circuit Court of Appeals for the District to prevent the decision from taking effect.

To build the list of most-wanted suspects, Ramsey ordered a department-wide review of arrest warrants. Since last Monday, detectives across the city have been working their way through hundreds of cases to decide which ones to feature on a Web site and a series of new posters.

Cmdr. Winston Robinson forwarded the names of five suspects from the 7th District, including White and Stewart, for whom there was no further information available. The other cases were a homicide, a stabbing and a beating.

Robinson apologized for not delivering 6th District names at the same time, explaining that detectives had just learned that at least two of their five leading suspects are already behind bars.

The revised 6th District list, which arrived via fax, included three assaults, a murder and an alleged sexual assault by a boy who, according to police records, turned 11 last month.

One of the five people is a suspect in the Dec. 11, 1997, murder of Troy Lee Gregory. He is identified by police as Mahdee Bryant, 22, who goes by the name Fats. A former resident of the 3400 block of Minnesota Avenue SE, he is described as being 6-foot-2 and weighing 300 pounds.

One aspect of Ramsey's plan is to name 10 suspects from each of three sectors of the city, on the theory that the odds of capture will increase if neighborhoods closer to the crime are put on the lookout for suspected bad guys.

"You might have a criminal active in the 6th or 7th District who never travels to Northwest," Ramsey said. "The priority will be on violent offenders. We might have one or two committing large property crimes."

Ramsey said the police department will make its own decisions about which suspects to feature, although prosecutors hope to influence the choices. A senior prosecutor suggested that police units and warrant squads should devote particular attention to people suspected of violent--and continued--law-breaking.
